Mine certainly isn't much of an ST-70. The driver and power supply are from Curcio, the output tubes are 6B4G, cathode biased. The rectifier tube is a 5U4GT. No negative feedback.
The only original parts are the transformers, the chassis, the speaker screw terminals (no, I've never replaced them), and the power cord may be original, or it may be a crappy replacement. Pretty sure the power switch is original. There may be a few wiring posts in there that are original, I don't remember at this point.
Nope, not an ST-70.
