Krell KSA-80 Power Amplifier Repair and Restoration New Transistors, Diodes and Capacitors

This Krell came in with a buzzing sound in one channel. The Krell Repair centre had performed repairs on it, which did not resolve the issue. We replaced all the Power transistors and driver transistors with matched units. Also replaced various diodes and some varied resistors. The unit sounds excellent and no more buzzing sound.
