Technics SA-1000
Little is documented about the Technics SA-1000 beyond its appearance in period advertising. There is no manual, no production dates, and no independent lab test in the archive yet. The record shows this much. Technics's launch ads, in HI-Fi-Stereo-Buyers (July 1978, p.86) and Audio (August 1978, p.116), introduced it as the most powerful receiver the company had made to that point. They advertised 330 watts per channel minimum RMS into 8 ohms from 20 Hz to 20 kHz, with no more than 0.03% total harmonic distortion.
The same ads pushed dynamic range in the amplifier section: 72,000 µF of high-capacitance filtering, separate DC rectifiers, current-mirror loading, and direct coupling. That is about all the archive has. Original price, weight, dimensions, inputs, and production span are all unrecorded so far.
One misfiled item needs flagging. Two source chunks quote an Audio review from September 1963 that praises an "SA-1000" as one of the finest amplifiers ever tested, citing 8417 output pentodes and a hinged cover. That does not match the late-1970s Technics receiver in the ads above. The Archive treats it as a different model and does not pin 1960s tube specs on this SA-1000.
