Peachtree Audio Grand Integrated X1 Stereo Amplifier. Buzz on one channel. Successful failure



Published
A customer brought me a Peachtree Audio Grand Integrated X1 Stereo Amplifier with a buzz on one channel. I think he waited a bit too long and caused some damage that I could not repair. I think the digital processing controller has failed and I could not find a replacement part, I had to return it to the customer unrepaired.
