1  Ceriatone / Overtone / Adjusting Preamp voltages in OTS 50(?) on: October 19, 2013, 05:14:56 PM
Greetings everyone,
I just completed my OTS 50 build and although I have moderately high voltages in the power amp section (472 CT, 470 on plates and screens), my preamp voltages are off the charts (V1 pin 1 363V pin 6 366V;  V2 pin 1 369V pin 6 241; V3 pin 1 304V pin 6 294V). Do I need to adjust the resistor values in the power supply to the preamp section or should I be looking for something else?  Thank you for your assistance.

Paul
