Dynaco ST-400

Little is documented about the Dynaco ST-400. The only known period reference is a classified advertisement listing a used unit for $295 (Audio, December 1980, p.93). That ad says the ST-400 was a power amplifier from Dynaco (Audio, December 1980, p.93). It also shows the model was in circulation by that date. Past that one listing, no specifications have been confirmed in period sources or surviving documentation. That means no power output, frequency response, weight or dimensions. Where it sat in the product line, next to the tube classics (Stereo 70, Mark III) or the other solid-state models (ST-80, ST-120), is unrecorded.

If you own an ST-400, have a manual, or recall its specs, the Archive would welcome a note.
