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.
