From: a@b.com The Allen 75 schematic has DC idle voltages and AC voltage at clipping. The 6SN7 CF has 385 VDC on the plate and -52 VDC for the cathode at idle. The bias supply is -120V and the cathode resistor is 23K 10W. The grid is at -71VDC. At clipping the AC cathode voltage is 38VAC. I will post schematic in a.b.schematics.electronic --- SoupGate-Win32 v1.05 * Origin: you cannot sedate... all the things you hate (1:229/2) |
