I believe I have a problem with the power supply in my old ATI 1506 amp. I talked to a tech at Jensen Transformers and he believes this is the likely cause of the buzz coming from my right front channel. In fact, he is almost certain of it. I live in the Atlanta, GA area. How does one go about finding a repair shop for an amplifier? And if the power supply needs to be replaced in one of the channels, about what would a repair like this cost?
