ARC D-75A
Almost nothing is documented about the ARC D-75A. Period classified ads confirm the model existed. It appears alongside the D-100A, D-52, and D-51 in listings from the early 1980s, such as an Audio classified (January 1982, p.79) offering a 'D-75-A-G'. No original specifications, brochures, service manuals, or editorial reviews have turned up in the usual archives. Even basic facts like power output, dimensions, and production years remain unconfirmed.
The few fragmentary references that survive:
- A later Audio classified (January 1982, p.79) offered a "D-75-A-G, mint cond. w/carton $695," again grouped with other ARC models.
- A Sound-Arts advertisement from October 1978 (p.49) described the closely related D-75 as delivering 75 watts continuous average power into 4 ohms in stereo, with a rear-panel switch converting it to mono at 95 watts into 8 ohms. The D-75A presumably shared or improved upon this design, but no source confirms it directly.
Nobody has recorded whether the "A" suffix marks a revision, a variant for a specific market, or something else. The D-75A shows up by name in period listings, but its real specifications and history are lost. If you have documentation, a service manual, or even a clear photograph, the Archive would welcome the contribution.
