WARNING: Tube/Valve amplifiers use potentially LETHAL HIGH VOLTAGES.
Building, troubleshooting and testing of these amplifiers should only be
performed by someone who is thoroughly familiar with
the safety precautions around high voltages.
Stereo integrated, vintage early 60s. outputs 7591, 2/side.
They Ks are tied together and a low value R is between them and ground. Has both bias and balance pots for each side. Any help or links to help much appreciated.
It wouldn't be a bad idea to learn how to use search engines; they're amazingly useful. Putting "Scott amplifier 233" into Yahoo and following a link got me this in about 10 seconds.
