Can anyone identify these parts I find in my 575 curve tracer. Is this a mod that tek made?
The dc balance doesn¡¯t adjust properly, and the dc adjust pots appear to have been replaced with much higher resistances. This is in vertical and horizontal amplifiers.
Can I check the heater voltages of the remaining 12au6s in the string by identifying the cathode pins and measuring the voltage across them?
Please help me with these questions
Sincerely,
Jack
