Dynaco Stereo 80 ST-80 Amplifier. Has All 4 Original Feet. Cord Has No Cracks. No Signs Of Corrosion. Lamp On Power Switch Works. Outstanding Condition And Sonics. Please Examine Photos Closely For Cosmetic Condition. Other items From My Collection May Be Viewed In My Listings. A rare piece greatly appreciated by audiophiles and not often seen. A Fantastic Addition To Any Vintage Collection. Power output: 40 watts per channel into 8? (stereo). Frequency response: 10Hz to 50kHz. Total harmonic distortion: 0.5%. Input sensitivity: 1.3V. Signal to noise ratio: 90dB. Speaker load impedance: 4? To 16? Semiconductors: 12 x transistors, 10 x diodes. Dimensions: 14 x 8 x 4 inches. The Dynaco Stereo 80 is an all silicon transistor basic power amplifier for use with separate preamplifiers such as the Dynaco PAT-4 or PAT-5 or for use with tape recorders or tuners such as the Dynaco FM-5 which have their own volume controls. The unit contains two 40 watt amplifiers on one chassis with a common power supply. It has been designed to be used under normal conditions without special safety precautions, just as if it were a high grade tube amplifier. There are no circuit breakers, speaker fuses, or other resettable devices to impede the use of the Stereo 80 under any reasonable conditions of use or abuse. This is achieved by using novel circuits (on which patents are pending) which automatically and instantly protect the amplifier. The components are of the highest quality to protect against failure, both now and for many years in the future. All parts are used conservatively with close tolerances to assure proper operation, and etched circuit modules are pretested under actual use conditions to ensure that every unit, after assembly, will meet the specifications normally associated with laboratory prototypes. The specifications of the Stereo 80 speak for themselves. The distortion at low levels is comparable to that of the finest tube designs, while the high power distortion remains inaudible. See my other auctions for a matching Dynaco PAT-4 Stereo Preamplifier to mate with this. Please check my other auctions for more vintage electronics.

As always, these amps are wonderful but too bad I’m limited in space so I can’t keep all the gear I find! See photos for physical condition of the outside and inside of the amp. FYI, the mono switch is noisy if engaged, and the power switch can cause a small pop if not flipped quickly. They both will eventually need to be replaced but I don’t have the time. Restoration included: HIGH quality F&T electrolytic caps; new coupling caps for the driver board; replaced the selenium rectifier with a diode, and added diodes prior to the rectifier tube for added power supply stability. Swapped out the 7199s with a pair of 6UA8s from Tube Depot back in June. Probably have 10 hours on them. Tubes are not guaranteed as I don’t have a tube tester. Tubes included are 4 mixed EL-34s, and 2 6UA8s, Tung Sol GZ34. Here’s video of the actual unit in my system. Photos demonstrate the physical condition. I’m in Palm Springs, CA 92262.

Vintage Dynaco Dynakit Stereo 70 ST-70 Amplifier Tube Amp & Cage – Mullard Tubes. Fully tested and 100% functional; this amp will provide that nice warm tube sound to your home stereo system. Tubes are all excellent. The tube complement is all Mullard – 4 x EL34, 2 x ECF82 and 1 x GZ34. The speaker posts were upgraded by the original owner to banana jacks (the right jacks exhibit some wear but nothing that affects performance). In upgrading the jacks, the 16 ohm output has been disabled. The RCAs look to have also been upgraded. Cosmetically, it is overall very good exhibiting only normal wear from over the years. Includes original cage (one screw for the cage does not match). Also includes a copy of the manual/schematic.
