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 have a tube amp which I am trying to identify. On the faceplate it says Gubin Valve Stereo Amplifier, precision audio component by Gloria, super linear circuit. It is a 2 x 100W p-p Russian tubes.
