RARE, ORIGINAL, WORKS GREAT! High Quality, American Made, Point-to-point wiring. This is a VINTAGE 1976 SANO SUPER NOVA STEREO TUBE AMPLIFIER. Designed to be used for guitar and I suppose accordion. It is complete and functions properly. Controls and inputs have been cleaned, no scratchy pots. Everything works as it should. The cabinet covering shows light wear. The grill cloth is in great shape. This is a solid, road worthy beast; weighs 65 lbs.. Each channel has volume, treble and bass controls. The stereo channel has a second input stage with treble volume and bass volume controls. There are push buttons to engage the reverb and tremolo for each/either/both channels. Made in the U. I honestly believe I was the first person to ever open the back of this amplifier. Nothing has been touched for 44 years. Original transformers, speakers, pots, electrical components, tubes, etc. From what I can tell the amp is completely original with the exception of one of the knobs. Power amp tube lineup… 2-GE 12AU7, Westinghouse 5U4GB rectifier, 2-GE 8417 power tubes. The preamp tubes are also all original… One United Electron 6FQ7 and the balance are USA General electric 9 pins (2-12AX7′s and 2-12AU7′s or 12AT7′s). This has the original 2 prong cord. The side of the fuse holder is damaged and you should consider replacing it if/when you decide to upgrade to a grounded power cord. The speakers are original to the amplifier. Square magnet, Eminence made, 67-7548 codes, so made the 48th week of 1975. Look like they could easily handle 50 watts a piece. This is definitely a clean amp. And I’m saying clean all the way up the volume dial. The 8417 power tubes are designed for high fidelity and that is exactly what you get. Full bass, rich midrange and crystal clear highs. Serious Jazz, acoustic electric and classic country players will love this amp. I would guess it puts out 50-60 watts. Rock and rollers should also consider this amp. This would make a great foundation for pedals if you want your sound to remain constant at all volumes. The tremolo and reverb are very well designed and rival that of the best Fender, Traynor or Ampeg from the same era. That is a bargain. This item is heavy and will require extra time and care to package. I never use UPS. Old electronics are scratched, worn, chipped, cracked, dirty, dusty, stained, ugly, tinkered with, missing parts, etc. The exteriors have wear that includes cuts, holes, tears, scuffs, missing stitching, missing or replaced feet and knobs. In the course of servicing over the years, they typically do not have all original components. Old electronics typically hum and have scratchy controls. As a basic test I have operated this amp for at least 4 hour recently and it did not fail, smoke, blow fuses, etc. Typically easy and inexpensive to maintain, you should be aware, old electronic require maintenance. Old electronic can fail at any time. We will work through the claim together until things are right.

Vintage Dynakit ST-70 Stereo Tube Amp Power Amplifier UNTESTED

Vintage Dynakit ST-70 Stereo Tube Amp Power Amplifier UNTESTED. Looks complete with all tubes and knobs. Missing the bottom metal plate & cage. Info found on the web. The Dynakit Stereo 70 is a complete dual 35 watt power amplifier kit which offers the highest possible fidelity, at low cost and in a compact arrangement. It uses a patented circuit of outstanding performance characteristics, along with top quality parts, including the new Dynaco Super-Fidelity A-470 transformers – the finest available. The measured specifications show that the Stereo 70 is an amplifier of unequalled performance, and its listening quality is also unrivalled by any regardless of price. The two non-interacting 35 watt channels provide adequate power, in a stereophonic or two channel system, for loudspeakers of any level of efficiency. The channels can be paralleled for a full 70 watts of low distortion output, suitable for practically any monophonic use even where several loudspeakers are in use in different areas. The high power capability and low internal impedance provide excellent damping for all types of high quality speaker systems without need to make adjustments to match specific speaker installations. The design features of your Dynakit which contribute to its superior listening quality include some which are not revealed by the customary steady-state laboratory measurements. For example, it does not exhibit bounce and flutter when pulsed with a transient signal. Thus a sharp percussive signal like a drum beat or a piano note will be reproduced with sharpness and clarity and neither overhang nor muddiness. The Stereo 70, unlike many other amplifier circuits, has been designed to provide its specified performance on a loudspeaker load, not just under laboratory measuring conditions. Therefore, the connection of a loudspeaker to the amplifier does not deteriorate its performance or listening quality. Power output: 35 watts per channel into 8 (stereo). Frequency response: 10Hz to 40kHz. Total harmonic distortion: 1%. Input sensitivity: 1.3V. Signal to noise ratio: 90dB. Speaker load impedance: 4 to 16. Valve complement: 4 x EL34, 2 x 7199, 1 x GZ34. I do not have the proper equipment to test a tube amp and do not want to risk applying power to a 60 year old unit. Previous units that I acquired from the same audiophile collection have proven to be in very good condition. He did not own junk. See pics for details. Will be carefully packed in a sturdy box with ample packaging. On all 6 sides. The Last pictures is an example of how I pack these (with Styrofoam on the top and bottom as well as the sides shown). It is located in Simi Valley, CA. Just 40 miles north of Los Angeles. The item “Vintage Dynakit ST-70 Stereo Tube Amp Power Amplifier UNTESTED” is in sale since Friday, January 8, 2021. This item is in the category “Consumer Electronics\Vintage Electronics\Vintage Audio & Video\Vintage Amplifiers & Tube Amps”. The seller is “duneedeals” and is located in Simi Valley, California.

Magical – very musical with a highly detailed voice and plenty of solid, clean wonderful bass. This amp is absolutely dead quiet – no hum, no buzz, no hiss, no snap-crackle-pop! It sounds like it is supposed to. If you’re in search of that golden age of audio sound with stunning vintage looks, you’ve just found it. This is your bad boy. This is a 100% brand new amp, a very high quality build, total listening satisfaction. This ST-70 delivers dramatically improved sonics as the result of being carefully and thoughtfully built, all new, from the ground up, with technologically advanced components and all high-end parts. Is used with only a couple of re-engineered elements on the PCB solder traces to accommodate the 6GH8A tubes without having to use an adapter. Enjoy the rich smooth tones of analog audio and even order harmonics that only vacuum tube amplification can produce. It reveals musical qualities with fantastic realism and depth you may have never imagined possible. The legendary original design up to date with highly improved levels of sound quality, looks and performance. Because of the ST-70′s naturally high impedance (470K) it is compatible with virtually any solid state or tube preamp. This amplifier puts out 70 watts total, 35 watts per channel. It is fairly safe to say that most people today would have no idea of how wonderful a Stereo 70 amplifier is capable of sounding like. “Original condition” amps or those “updated” or having any number of “modifications” from mild to wild can still leave a lot to be desired. “Restored” is more than popping in a few capacitors and some tubes. Much more will need to be done to fully bring about that great sound the amp once had. Although they will play music, they are still incapable of reproducing the sound quality they possessed when new, 50 years ago unless they are fully restored. Resistors become noisy and drift out of tolerance due to age and heat. Circuit board and component materials begin to deteriorate causing signal degradation, solder joints and tube sockets can be loose, oxidized, worn and have poor quality connections causing signal interference and noise. Capacitors lose their range and clarity, their values having changed with time. Hiss, buzz, hum, pop and fuzziness are not normal or desirable qualities. Isn’t the great smooth sound of a time long gone by what you’re really after, those sweet tones produced only from tube amplification? Like a musical time machine, this amplifier will take you back to the beginning, like when these amps were new. But there’s even more to consider here. All of the components used in this amplifier have greatly improved characteristics over the ones available and used 50 years ago. That makes the sound quality of this amp even better than one would have been then, as a new one 50 years ago. Take a good close look at this one. Don’t cheat yourself out of what you’re really wanting; superb sound, high build quality, safe and reliable operation, great looks and that comforting pride of ownership. Pay particular attention to the size (height) of the power transformer on this amp (the middle one). Transformers are the heart and soul of a tube amp, period. Dynaco wasn’t messing around when they designed and built their originals. Notice how tall this new Dynakit transformer is compared to the original Dynaco PA060 power transformer. This is a real case of bigger is better. These new Dynakit transformers were reverse engineered from the original Dynaco designs using modern technologies and insulations. An increased lamination stack on this power transformer allows it to run cooler and provide better regulation. These transformers wont buzz or hum like the originals often do either. A major factor to consider here too is that the original transformers were designed to run from yesterday’s 117 Volt household current. Today’s household current is often 125 Volts or more so the use of a “step down” or “bucking” transformer is necessary to retard the voltage down to a safe operating level for amps having the original transformers. The new transformers are made for today’s higher household currents or VAC (Voltage). These transformers can be operated directly from your household outlets without secondary devices needed to reduce the voltage. These are USA made transformers that meet and exceed every aspect of the originals. If there were some sort of “magic” in the use of cloth leads, Dynakit would have certainly insisted on using them again. There’s simply no magic in cloth covered lead wire, period, it is inferior. In any comparison, these new transformers are just better than those old originals. Modern advancements in materials, methods and technologies used in the production of these transformers has resulted in superb transformers that operate quieter and cooler than the originals while providing less distortion, more power with increased reliability. The new A470 output transformers are also greatly improved, like the power transformer. The output transformers are interleaved/layer-wound and incorporate high quality M-6 grain oriented laminations. These also use better quality wire with better insulation, the primary is wound the same as the original A470 using the same number of turns on the same number of sections. These are made using the same patented Dynaco winding method, and made on the same core size and material type as the originals. These transformers are in one word, exceptional. I have selected the Groove Tubes 5AR4/GZ34 as the rectifier tube in my Dynaco 70′s for more than 2 years now. It has the highest current capability and has been 100% reliable, it also looks right at home in the amp. I believe it to be the best current production rectifier tube of its type on today’s market. Same story for the NessTone EL34/6CA7 tubes, they’re all I use now. These output tubes are hand selected and tested here in the USA and then identically matched as a quad (4 tubes) by their plate current test. Results using the ROE computerized testing system. I have had nothing but satisfied buyers and zero failures, they sound amazing. This amp also comes with 2 NOS RCA, GE or similar (as per availability) 6GH8A tubes, tested and matched. The 6GH8A like the 7199 tube is a vacuum tube combining both a pentode and triode in a single glass envelope. Each section has a separate cathode and is electrically independent, the pentode is used for the input stage, and the triode as a phase inverter. The Dynaco ST-70 Series II came from the factory with a 6GH8A driver board and tubes. According to Dynaco published research and literature the 6GH8A tube actually outperformed the 7199! I also offer this amp in a 7199 version, identical in build with the exception of the 7199 driver board and tubes. The photos show the ST-70 using the updated Dynakit PC-3 board made for 6GH8A tubes. Amplifier makers like HH Scott, Harman Kardon and Eico, among others, have used the 6GH8A since back in the late 50′s. I honestly find no audible difference in the 7199 and the 6GH8A so long as both tubes are of equal quality. Good quality tubes are essential for the overall sound quality simply because they are a part of the circuit, the circuit can only sound as good as it’s parts will allow. Good circuit design is critical, the Dynaco circuit is genius. The 6GH8A, also no longer in production, appears to be in abundant supply and is very affordable. Like all tubes, some brands and build styles offer both sonic and reliability advantages over cheaper, inferior made tubes. This amp comes with 2 NOS RCA, GE or a Mullard variant (as per availability) 6GH8A tubes, tested and matched. Contact me if you want the 7199 version, I’ll make a special listing for you. Tube installation instructions with a numbered easy to follow pictorial is included. Bias will be pre-set but due to variations in AC wall voltages the bias should be checked and adjusted as necessary for your specific location. Proper bias is essential for best sound quality and performance of the amplifier. Proper bias is also key to getting the most life out of your tubes. You are responsible for proper bias adjustment and maintenance, you will need a voltmeter that measures/reads DC volts and a small slot head screwdriver to turn the adjusters and to remove and reinstall the amplifiers cover. Bias should be set to 1.56 volts DC. Each unit is custom, a hand built, made to order unit. Your unit will look identical but wire color and routing may be slightly different from unit to unit, these are hand built units. Turnaround time is running 4-5 weeks right now. The manual with instructions, pictorials, diagrams, schematics and supplemental documentation is included. The item “NEW!

A DETAILED DESCRIPTION OF THIS RARE VINTAGE TUBE AMPLIFIER IS PROVIDED AFTER THE PHOTOS. PLEASE SCROLL DOWN TO SEE THE DESCRIPTION. It has a very distinctive retro and industrial look to it. Also, it is really attractive-looking and in very good cosmetic condition in my view. It was carefully wrapped up in cloth and stored in a box that I found down in the basement. I wasnt going to sell this amp since it is so cool-looking but I decided to sell it and let it go to a new home where someone can appreciate and enjoy it. DETAILED INFORMATION INVOLVING THE AMPLIFIER. As the photos show, this amp has a very interesting, unique, and distinctive look to it as mentioned above and it would make a wonderful addition to any vintage electronic collection. It also has a very unusual retro/industrial appearance and is in beautiful cosmetic condition in my opinion. Ive never seen another amp which looks quite like it. Check out all of the many photos of it that I have provided which show both the inside and outside of the amp. The amplifier is a Heathkit Stereo Tube Amplifier Model SA-2. It has a very distinctive front faceplate as the photos show. The graphics do show some wear for example, the SA-2 model no. Is faint, worn, etc. But, as a whole, they look fairly good in my opinion. Please check out the various photos which show the front faceplate and the graphics. There is also a nice-looking metal bronze-colored trim-piece on the front faceplate as shown in the photos which is in great condition in my view. The trim-piece also has a retro stylized HEATHKIT logo on it which looks very attractive as shown in the photos. The cabinet in is really nice cosmetic condition in my opinion. While the cabinet does have some nicks, scratches, scrapes, cuts, a bit of paint-residue, etc. On it (see the many photos of it that I have provided), it is again my opinion that it is in really nice condition and I believe that it would be difficult to find one that is better cosmetically. It looks like this amp did not get a lot of use, wear, etc. Based on its nice cosmetic condition although I dont know for sure if this is the case or not since I dont really know anything about the history of this amp. However, I think that it is one of the most stylish and unique-looking amps that I have ever seen! The amplifier chassis is shown in detail in the photos. It looks really nice in my view and has a nice shine to it. It is also very clean, too. While the chassis has some scratches, scrapes, dents, scuffs, residue, bends, discoloration, dirt, etc. On it, the chassis looks very good in my opinion as shown in the photos. There appears to be a few pieces of black tape on the rear of the chassis. I don’t what these are and how easily they are removed (if desired). However, the chassis used by this amplifier is one of the cleanest and shiniest that I have seen and really looks nice in my opinion. Regarding the knobs, they are all present and appear to be original based on what Ive seen on the Internet. The knobs are very cool and distinctive-looking. They have some wear on them, but in my view, they really look nice with their shiny brass metal inserts and give the entire amp a very unique and distinctive look unlike any other amp that Ive ever come across. I have provided a number of photos of the amplifier chassis. This amp has not been tested and I have no idea as to the condition of the tubes, electronic components, wires, transformers, switches, controls, fuse, fuse-holder, and the other components, parts, etc. Associated with this amp. In addition, I do not know if all of the parts, components, and elements associated with this amp are original or not. I likewise have no idea whether anything is missing from the amp and its various electronic components, controls, switches, transformers, etc. I also have no idea if this amp has ever been worked on, serviced, and/or repaired or not. I have not inspected or done anything to any of the components, parts, switches, controls, sockets, tubes, transformers, etc. Inside and outside of this amp and I know nothing about their condition. Furthermore, it should be assumed that this amplifier is not working and that it will need service, repair, parts, components, tubes, or a combination of these items. Please make a note of this. However, the amp has a very good cosmetic appearance in my view and check out all of the photos of the amplifier which show it from various angles. The amplifier has a bottom plate which is shown in the photos. The bottom plate is nice, clean, and shiny. While it has a number of scratches, scrapes, dings, dents, bends, scuffs, dirt, discoloration, etc. From age, use, etc. It looks very good in my view. The bottom plate is held in position using a number of screws as shown in the photos and I do not know if the screws are original or not or if they are correct for this amplifier. The bottom plate has a number of slots, openings, etc. On it and, in addition, an open area which exposes a number of jacks, etc. Likewise, there are some paper labels attached to the bottom plate adjacent these jacks and various other controls which evidently provides some kind of identifying information regarding these items. I do not know what this identifying information involves and if, in fact, it involves identifying information regarding the jacks, controls, etc. The paper labels discussed above do have some worn areas, rough spots, discoloration, etc. On them but they are mostly readable and look nice as the photos show. Likewise, there are 4 plastic feet attached to the bottom plate using screws. These feet do not appear to be original although I do not know if they are original or not. The feet are in decent condition in my opinion although they do have a number of scuffs, scratches, scrapes, discoloration, etc. On them from use and age. Regarding all of the jacks/controls on the bottom of the amplifier as well as the controls on the front of the amplifier, the other controls which are used by the amplifier, and all of the amplifiers other components, parts, and elements, I have no idea if they are original, complete, operational, functional, properly wired/installed, or correct for this amplifier and, accordingly, I will again leave an assessment of all of these items and the amplifier as a whole, as well as its tubes, fuse, fuse-holder, etc. Furthermore, there are a number of screws on the bottom of the amp which hold the cabinet in position. I dont know if these screws are original or not, if they are correct for this amplifier, etc. They also might be a bit difficult to remove. At the rear of the amp, there are a number of components including a pair of outlets, two large terminal strips with multiple screw-terminals thereon, some kind of a wire extending outward from the amplifier chassis and connected to one of the screw terminals, a slide switch, and a fuse holder. I have no idea whether these outlets are good, correct for this amp, functional, operational, wired correctly, etc. I also do not know what they are supposed to do. I will therefore leave an assessment of these outlets as well as all of the amplifiers other parts, components, tubes, wires, transformers, controls, switches, jacks, power cord/plug, tubes, fuse, fuse-holder, etc. I did notice that at least some of the screws on the terminal strips have what appears to be some colored marking-pen ink on them. I don’t know anything about this. Regarding the power cord/plug, I dont know if it is original or not, if it is good or not, if it is wired correctly or not, and if it is the correct and appropriate one for this amp. Regarding the tubes which are included with this amp (and were in it when I bought it), they are as follows: (A) 6BQ5 (USA); (B) 6BQ5 (USA); (C) 6BQ5 (USA); (D) 6BQ5 (USA); (E) 6AN8A GT. BRITAIN; (F) 6AN8A GT. BRITAIN; (G) 6AU6A (USA); (H) 6AU6 (USA); (I) ECC83/12AX7 GT. BRITAIN; (J) ECC83/12AX7 GT. BRITAIN; and (K) a larger tube which has no tube-number on it (made in GREAT BRITAIN). However, I noticed some codes etched in the glass as follows: f 3 1 and B 9 E. From what Ive read on the Internet, these codes indicate that the tube is a GZ34 possibly made by Mullard. Nonetheless, I do not know if this information is correct or not and if I have read the codes correctly or not since they are very hard to see. Accordingly, I cannot make any guarantees regarding this tube and whether it is correct or not for this amplifier and whether it is good or not. Likewise, regarding all of the above-listed tubes, I do not know if they are good or not, if they are correct for this amplifier, if they are in the correct sockets, etc. And I have not tested them. Likewise, the graphics are smudged/missing/faint on the tubes to varying degrees. As stated above, I also dont know if these tubes are the correct ones for this amp, if they are original or not, and if they are in the correct sockets. Also, I did not check the tube sockets and I likewise cannot warrant or guarantee that they are good, original, functional, fully-intact, and operational. Likewise, I did not inspect or test the fuse and fuse holder which are used by this amplifier. In this regard, I dont know if the fuse holder is functional, original, and wired correctly, and I likewise do not know if the fuse is the correct one for this amplifier and if the fuse is good or not. I also did not inspect this amplifier for damage, missing parts, broken parts, replaced parts, incorrect parts, etc. And I likewise did not inspect any of the other internal or external controls, parts, wires, resistors, transformers, capacitors, switches, jacks, outlets, power cord/plug, fuse, fuse holder, terminals, or any of the other components associated with this amp and I will likewise leave any assessment of these items and everything else associated with this amp and its tubes, parts, components, fuse, controls, etc. Regarding the various controls used by this amplifier, I did not operate them, I did not test them, and I know nothing about their condition. In addition, the amp includes 2 metal tube-shields which are positioned over the 12AX7 tubes. I dont know if these tube shields are original, correct for this amplifier, placed on the correct tubes or not, etc. The tube-shields look decent in my view although they do have some wear, scratches, discoloration, etc. On them, most likely from age, use, etc. Furthermore, this amp includes a very cool-looking red-colored indicator light on the front of the amp which is shown in the photos. I have not tested this indicator light and I dont know whether it is good or not or if it is correct for this amplifier or not. I also dont know if it is original or not. The amplifier chassis has a main power transformer and 2 output transformers. I do not know anything about these transformers, if they are good or not, if they are original or not, and if they are wired correctly or not. These transformers can be seen in the various photos of the chassis that I have provided. These seems to be some kind of residue on top of one of the output transformers. It may have come this way from the factory, but I dont know whether or not this is the case. I also dont know if any or all of the transformers are original or not, if they have been replaced at some time in the past, etc. And if they are operational/functional. As previously noted, I have provided various views of the amplifier chassis in the photos. I have no idea if the wiring in the amp is correct or good and I dont know anything about any of the electronic components capacitors, resistors, outlets, controls, switches, tubes, wires, power cord/plug, transformers, jacks, fuse holder, terminal strips, fuse, etc. Associated with the amp. Specifically, I dont know whether or not these components and all of the other components/parts/elements associated with the amp are good, correct, original, functional, properly-wired, operational, etc. And I also dont know whether or not there are any missing, replaced, and/or incomplete components and parts. In addition, I dont know anything about the condition of the resistors, capacitors, wires, transformers, tubes, controls, fuse holder, fuse, switches, jacks, outlets, power cord/plug, wires, terminal strips, etc. And whether or not they are original, functional, correct for this amp, etc. Likewise, it should also be noted that Heathkit products were designed to be assembled by their purchasers and, in this regard, I cannot provide any representations, guarantees, warranties, or conclusions concerning the assembly of this amp and whether or not it was assembled properly and put together in accordance with Heathkits instructional materials. Accordingly, I did not conduct an in-depth or detailed inspection of this amp for damage, missing parts, broken parts, incorrect parts, incomplete parts, improperly assembled parts and circuitry, repaired parts, etc. Likewise, I would encourage a detailed overview of the many photos of this amp inside and out that I have provided since these photos should be considered to be an important and integral part of the current description of this amp. Furthermore, there may be various issues, damages, missing parts, incorrect parts, incomplete parts, inoperative parts, improperly assembled parts and circuitry, repaired parts, replaced parts, etc. In conclusion, this is an unusual and unique amp with a very interesting retro appearance. It looks like it is in great cosmetic condition and is really a beautiful amp in my view. Accordingly, it would make a great addition to any vintage electronic collection. Are original or not and whether the amplifier is complete. I have not done anything to this amp and all of its parts, transformers, wires, electronic components, tubes, sockets, fuse, fuse holder, capacitors, resistors, jacks, switches, controls, wires, power cord/plug, outlets, indicator light and all of its other components and I know nothing about their condition. The above-described amp may have been worked on, repaired, and/or modified by someone else in the past, but I dont know whether this is true or not. In this regard, I have done nothing to this amp and I have not inspected it internally or externally and have not tested it or any of its parts, tubes, indicator light, fuse, fuse holder, controls, switches, jacks, outlets, power cord/plug, outlets, transformers, etc. No other items such as boxes, cartons, paperwork, manuals, literature, carrying cases, accessories, or anything else are included. However, I do not know how much work, parts, wires, wiring work/replacement, repairs, rewiring, transformers, electronic components, power cord/plug, controls, switches, tubes, jacks, fuse, fuse holder, sockets, resistors, capacitors, outlets, indicator light, or other components/parts, etc. This amp is heavy (it weighs approximately 25 pounds packed). This amp has been very carefully packed/wrapped and is double-boxed. While I will pack this amp very securely, some of the wires, components, parts, capacitors, resistors, sockets, transformers, jacks, indicator light, fuse, fuse holder, sockets, controls, knobs, switches, screws, faceplate, trim-piece on the faceplate, Heathkit logo, power cord/plug, and other parts/components etc. However, I have done my best to try and prevent these situations by very carefully packing and double-boxing this amp although I cannot guarantee that they wont happen. Furthermore, all of the tubes, sockets, capacitors, resistors, jacks, transformers, switches, power cord/plug, indicator light, controls, outlets, fuse, fuse holder, and all of the amps other components/parts need to be checked out by an electronic expert to see if the tubes are good, if the tubes are the correct ones for this amp, if the tubes are in the correct sockets, if the fuse is good, if the fuse is the correct one for this amplifier, if the fuse holder is good/correct, and if all of the tubes, capacitors, resistors, jacks, transformers, sockets, power cord/plug, wiring, indicator light, outlets, switches, controls, and all of the amps other components/parts are good, functional, correct for this amp, and operational. This needs to be done before the amp is powered-up, tested, used, worked on, connected to any other equipment, instruments, or components, connected to a power source/supply, handled, repaired, modified, upgraded, etc. Likewise, I have no idea whether everything is original or not in the above-listed equipment and I therefore cannot make any warranties regarding originality. I also do not warrant that this amp is complete and I do not know if there are any missing, damaged, incomplete, previously repaired/replaced parts, malfunctioning or incorrect parts, components, tubes, fuse, fuse-holder, etc. The item “BEAUTIFUL RARE VINTAGE HEATHKIT SA-2 QUAD EL84 STEREO TUBE AMP AMPLIFIER” is in sale since Sunday, January 3, 2021.
