Vintage Tube Amp

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. 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).
