To err on the side of caution, I'll probably remove the SCR sweep module anyway. Since these are SS sets, but unusual ones, is there anything I need to know when starting them with a variac?
The fellow said the GR-370 had some kind of vertical problem but I forget what. The vertical oscillator has been replaced; the old one was floating around in the cabinet. The loose one uses carbon composition resistors on it whereas the replacement uses carbon film.
