Dynaco 200
A phantom model designation with no confirmed documentation, production years, or specifications.
Overview
The Dynaco 200 is a ghost. Period catalogs, magazine indices, service manuals and owner registries turn up nothing under this designation. No production years are known. No original price has been established. No chassis photographs, no schematics, not even a passing mention in Dynaco's own literature. Dynaco is a thoroughly documented company, and the ST-70, PAS-3 and Mark III have generated decades of enthusiast literature. A model number with zero paper trail is genuinely unusual.
What the archive does confirm is that Dynaco's amplifier engineering from the late 1960s through the mid-1970s centered on specific power benchmarks. The Stereo 400 was a solid-state unit rated conservatively at 200 watts per channel into 8 ohms. Audio (May 1975, p.48) called it "a rugged, solidly-built 200-watts-per-channel power amplifier." It was available as a kit for $499 or factory-wired at $669. The same review noted it weighed 52 pounds net and drew 11 amps maximum. Those numbers point to serious transformer and heat-sink work. Whether the "200" designation started as shorthand for that 200-watt-per-channel figure, a prototype variant, a distributor-specific labeling scheme, or something else remains unconfirmed.
Dynaco's product names in this period followed a few patterns. The Stereo 120, Stereo 150, Stereo 400 and SCA series all tracked wattage or configuration. A standalone numeric "200" fits none of those conventions cleanly. Contemporary advertisements, including a spread in Audio (August 1975, p.15) promoting the Stereo 400 and Stereo 150, make no reference to any model designated "200." The designation does not appear in the company's kit-building catalogs, or in the service-bulletin archives maintained by successor entities.
No verified example of a Dynaco-branded product bearing the standalone model number "200" has been documented.
The entry exists here as a placeholder and a hedge. Vintage audio is full of regional variants, dealer-exclusive bundles, pre-production prototypes and cataloguing errors. If a Dynaco 200 surfaces with original packaging, a stamped chassis and corroborating documentation, this page will be revised.
