1 Pair of Vintage Marantz 5 Monoblock Amplifiers Tube Amp Lot. Units power on as we brought them up slowly on a variac, all tubes come on. These amps were acquired by us a couple years back from an audiophile collection, back then we did test them and seem to remember there was issues with one if not both of the meters but they were producing sound back then. Due to the age of the items we would recommend them being serviced either way. These are in relatively good condition for their age; there is some scratches, scuff marks, stains, chips and dings; there is some noticeable marks on the side of one of the amps. Also a previous owner etched #s on the back panels of both units; not sure if there is a trick to filling them in to make it less noticeable. These units are getting harder to find; we were hesitant to even list them as we know we probably won’t ever own another pair. This item is in the category “Consumer Electronics\Vintage Electronics\Vintage Audio & Video\Vintage Amplifiers & Tube Amps”. The seller is “audiollc” and is located in this country: US. This item can be shipped to United States.

Up for sale here is this neat vintage Voice of Music tube amplifier, marked 20010 87 on the chassis. This is circa 1958 and is Made in USA. It normally uses a 6CA4 rectifier tube, two EL84/6BQ5 output tubes, and a 12AU7 and a 6AU6, but only the 6AU6 is included, sorry. This is a mono amplifier–you could match it with another for stereo, you could rebuild it as a guitar amp, or just use it as a mono amp. This is in good physical condition with light overall wear. There is no bottom cover. Everything looks original to me. It will be an amazing guitar amp once it’s done. I will guarantee the transformers to be good. Look at those neat vintage caps! Please see my pictures for details. If you have any questions, please ask. I have more amplifiers and other vintage electronics listed–feel free to take a look!

Up for sale here is this single vintage Eico HF-20 tube amplifier, with serial number 7973. This came from a local tube guy, and came to me just as you see it. This is in fantastic condition, and includes all the tubes, the top cage/cover, and the bottom cover/feet as well. The bottom is missing a few screws, but has most of them. This is in really good physical condition, but here are some things to note. Light overall wear, some minor scrapes/scuffs. Knobs are all there and are in nice shape. Very light rust on transformers. Tubes are the ones that I got it with, and are untested. The outputs are a very mismatched pair–one is a 5881 and the other is a Sylvania 6L6GC. Cord is attached and seems fine. Circuitry may or may not be original–I don’t see anything modern, but I don’t know if this was ever updated. I will guarantee the transformers to be good. This is a really rare amp, especially in this condition–don’t miss it! Please see my pictures for details. If you have any questions, please ask.

No mid-fi, no gimmicks, no junk. Each piece of equipment is cosmetically restored and fully tested in our well-equipped lab by an engineer with 30+ years of experience in the HiFi world. Through our sister company, which is an authorized dealer for McIntosh, Audio Research, Sonus Faber, ClearAudio, Project, and Sony ES, we have access to OEM parts, service, and support. With regards to sound quality, the MC30 is considered to be the most desirable McIntosh model among audiophiles and collectors. It was only produced from 1954 to 1962, and unlike other McIntosh Tube amps there were no later model anniversary or commemorative editions produced. The restoration goal for this pair was to make these classics as reliable and as cosmetically clean as possible, without disturbing their special vintage sound quality. SkyFi Restoration Notes: New and professional reproduction chrome chassis. Multi-section filter can replaced, and new power resistors installed for the B+ Supply. Bias Diode replaced with a silicon unit. All signal path capacitors replaced with Solen branded polypropylene. Select out-of-spec resistors replaced on the peg boards. Bottom cover and transformers appear to have been repainted with textured matte black. New high quality RCA connectors. New Cinch barrier strips (also called a terminal block) for all speaker connections Both pieces have their original power cords but were reduced to 4 feet in length during the restoration for safety/to remove some past damage. Both MC30′s performed amazingly well on our bench tests. They are perfectly balanced to one another. Clipping at just under 35W each into 8 ohms. Tube Notes: Each MC30 is loaded with a carefully hand-selected set of vintage driver and rectifier type tubes. Alongside current production Tung-Sol 6L6GC output tubes. All tubes were tested and verified on our modern and professional Amplitrex AT-1000 tube tester. V1 – McIntosh 12AX7. V2 – NOS Philips ECG 6189W (12AU7). V3 – Vintage GE 12BH7. V4 – McIntosh 12AX7. Rectifiers – Sovtek 5U4G. Output Tubes – NEW Plate Current Matched Quad – Current Production Tung-Sol. Please see our photos or the above manual for full technical specifications and dimensions. The SkyFi Testing Process for Tube Amplifiers: We start with a visual inspection of all internal components to make sure there are no signs of stress or aging. Capacitors are checked for telltale sings of bulging or leaking, resistors are checked for signs of overheating or cracking, and tubes are inspected for signs of stress overheating or cracking. We then power up the unit carefully and run a simple 1k sine wave while monitoring the output on an oscilloscope for signs of distortion or noise. Finally we run the amplifier to its full rated power into the appropriate resistive load provided by our Sencore amplifier tester. If there is an issue, it will usually be noticeable at this point. If it all looks clean we will often test for THD (Total Harmonic Distortion) measured by our Keithley distortion meter, and compare it against the original manufacturers specifications. The amplifier the remains powered on to “burn in” on our test bench for a few hours to make sure there are no heat related issues. If there are balanced inputs available they will also be tested. We also test all tubes for output gain and leakage on our calibrated B&K 747 tester against the original manufacturers specifications. If needed, the tubes will be replaced from our vast NOS (New Old Stock) vintage or modern inventory. Final testing involves pushing actual music thorough the amplifier. We’ve learned over time that some issues are only noticeable to a trained ear while listening to familiar source material. Our test bench has reference vintage KEF speakers that we’re very familiar with which quickly reveal any discrepancies. Some amplifiers will then move into our listening room where they are tested with our in-house reference speakers of choice. If we dont have the original manufactures packaging, we use heavy duty double-ply corrugated boxes with custom made to your item Instapak expanding foam custom inserts. In many cases this has proven to be better than the original packaging! We also use high quality fiber reinforced tape to seal our packages. We have too many items for sale and its nearly impossible to keep track of offers outside of the official system. We accept trade-ins of equal or lesser value under certain conditions. Please visit our website to submit your gear for full consideration. We will only consider high-end equipment from mainstream manufacturers such as McIntosh, Mark Levinson, Audio Research, Krell, etc. And will typically pass on displays, projectors, receivers, dated surround processors, and mid-fi equipment of any type. We will offer a fair value for your equipment, but keep in mind were running a business and will need to be able to resell the equipment at a profit after investing a great deal of time and resources in testing, certifying, repairing, cleaning, and packaging the incoming equipment. SELL US YOUR GEAR (Working or Broken). Simply visit our website to submit your gear for full consideration. We are currently operating from our shop inside our dedicated building in Glen Rock, NJ.

No mid-fi, no gimmicks, no junk. Each piece of equipment is cosmetically restored and fully tested in our well-equipped lab by an engineer with 30+ years of experience in the HiFi world. Through our sister company, which is an authorized dealer for McIntosh, Audio Research, Sonus Faber, ClearAudio, Project, and Sony ES, we have access to OEM parts, service, and support. This listing is for a working set of Mark VI Monoblocks in working condition. Features rare XLR inputs for an amplifier this age. Cool bias meter on the front with rack handles. This pair of amplifiers is labeled “Dynaco Wired”, however they have underwent a significant modification at some point in the past. The majority of the electrolytic capacitors were replaced, film bypass capacitors were added to the various power supply rails, and slow start relay circuits were added to delay the B+ voltages. Other modifications may have been performed that we are unaware of that sharp Dynaco aficionados may recognize. Both amplifiers were tested to their rated power of 120W. Both meter lamps and meters are working properly. Tubes include RCA 7199, and a mix Sylvania and Philips USA 8417. Please see our pictures for overall condition. The Mark VI is a vacuum tube high power basic power amplifier designed for the professional sound installer. Vacuum tubes are most often favored in their ability to withstand enormous physical and electrical abuse – conditions frequently encountered in discotheques, public address and musical instrument applications. Its rugged construction and utilization of superior components, including the patented Dynaco Super Fidelity transformers, permit continuous duty at full power, while maintaining safe operating margins. Protective isolation of the load from the driving circuits, and uniform power output into a variety of load impedances are inherent in all designs which use an impedance matching transformer. The Mark VI employs a basic circuit arrangement which all Dynaco vacuum tube amplifiers have used since the inception of the Mark II amplifier in 1955. Refinements of the operating parameters have been incorporated for circuit balance, stability, and for drive capability. The components used have been selected to protect against failure, and all parts are operated conservatively to assure superior performance and proper operation for many years. The SkyFi Testing Process for Tube Amplifiers. We start with a visual inspection of all internal components to make sure there are no signs of stress or aging.

Non tested, but fuses are not blown. These Ampex tube amplifiers are well regarded for their build quality, particularly the Triad output transformers. These are a very clean all original pair, with only one non original output tube. The 12au7s and EF86 tubes are Amperex. The rest are GE with the exception of one Sylvania 6973. The cords are cut because they were crumbling when I removed them from the console, and they were basically bare wires. See preamp and tuner to be listed in the coming days.
