Harman Kardon PM655 Checkout & Repair

Описание к видео Harman Kardon PM655 Checkout & Repair

This is a Harman Kardon PM655 Integrated Amp I picked up recently. It was pretty rough when I got it. The switch for the loudness contour was missing altogether and the pre-amp/tone board had issues. Surprisingly, the old amp cleaned up pretty well after replacing the electrolytic capacitors, repairing some issues and adjusting the bias and balance. Too bad the loudness switch is made of unobtainium or this could have been a great restore project.
