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.
I can't find sovtek tubes there, but would all tubes of the same type (in my case 6922 and 6as7g) have the same pinouts? I gather they would for replacements, but I better make sure before I blow something up...
