ADC 600 (ca. 1966–1967)
Not much is documented about the ADC 600 beyond the ads that promoted it. The record shows a solid-state stereo receiver rated at 60 watts, priced at $219. ADC claimed it “set the trend in low cost quality receivers.” The same ad copy ran in several audio magazines from late 1966 into 1967 - High Fidelity (November 1966, p.24) and HiFI-Stereo (November 1966, p.22) both carried it, and it kept running into early 1967 (HiFI-Stereo, February 1967, p.14; High Fidelity, March 1967, p.14). The ads also mention a sibling model, the 606, which suggests the 600 was part of a short-lived receiver line.
No service manual, schematic, measured performance data or detailed specifications have turned up in surviving period sources. The front-panel layout, control complement, amplifier topology and production date range are all unconfirmed. The ads are the only certain facts.
