Technics ST-7600 (production years unconfirmed)
Little is documented about the Technics ST-7600. The record is thin. Production years, specifications and original price haven't been confirmed, and no period review specific to this model has surfaced. Going by the model number and Technics' component lineup of the era, it appears to have been a tuner, but that identification is inference, not documentation.
What the period record does show is indirect. Technics' early-1977 "waveform fidelity" advertising ran in High Fidelity (March 1977, p.19) and other magazines. It warned that a good amplifier and tuner could cost $350, $500, $700 or more, and argued that without faithful waveform reproduction, the music put in wouldn't be what comes out. The surviving copy of that campaign promotes the ST-8600. It cites an 8-ganged tuning capacitor (five sections for FM, three for AM) and a Technics-developed four-pole MOS FET. The ST-7600 is not named in that material.
The ST-7600 may well have been a sibling of the ST-8600 in the same tuner generation, but no specification sheet confirming that has been located. Until a manual, service sheet or catalogue page turns up, this page remains a stub. If you own an ST-7600, the Archive would be glad of the missing details.
