Fisher 500-C
A 36½-pound chassis that crammed an FM-stereo tuner, a stereo preamp, and a power amp into one box — and the reviewers of the day couldn't quite believe how well it worked.
Overview
The 500-C is the receiver that convinced a generation of listeners they didn't need separates. Fisher built it as a single-chassis combination of an FM/stereo tuner, a stereo preamplifier, and a stereo power amplifier, and the front panel is dominated by a generously sized tuning scale flanked by the usual controls.
The headline number is the amplifier rating: Fisher specified a 75-watt (IHF) stereo amplifier section. That IHF figure is the one to treat with care, because High Fidelity (March 1964, p.3) noted the discrepancy directly — the manufacturer's 75-watt IHF claim corresponded to roughly 60 watts total continuous output with both channels driven, and the magazine's own bench measured continuous output at about 70 watts at 1% distortion. In other words, the 500-C is honestly a 30-ish-watts-per-channel receiver by modern continuous standards, and it will drive reasonably efficient speakers without complaint. Buyers who expect a 75-watt-per-channel powerhouse from the badge will be disappointed; buyers who understand the IHF convention will find the amp section entirely respectable for its class and era.
High Fidelity (February 1964, p.63) gave the 500-C a full equipment profile and described it as the most comfortable "all-in-one" unit of its type up to that point. That's the pitch, and it holds up: the appeal of the 500-C is not raw power but integration. One box, one power cord, one set of speaker terminals, and a tuner that tracks FM stereo without a separate outboard multiplex adapter cluttering the shelf. For a listener in 1964 who wanted serious hi-fi without a component stack, this was the answer.
Collectors should note the serial-number range documented in Fisher's own service literature: chassis serials from 30001 to 49999 inclusive. That's the band to check when hunting for a unit, and it's worth confirming before you commit to a restoration, since parts and documentation are keyed to it. Fisher's own service manual for the model was published as a one-dollar item, which tells you something about how the company expected owners and technicians to work on these things — this was gear meant to be maintained, not thrown away.
The honest caveats are the usual ones for a 60-year-old tube receiver: expect to recap, expect to check the tuner alignment, and expect the weight to make shipping an expensive proposition. The 36½-pound figure is real, and a well-packed 500-C is not a cheap parcel. None of that is a knock on the design — it's simply the cost of admission for a piece of Fisher's all-in-one era that the contemporary press regarded as a benchmark in its class.
