Marantz 2220B Restoration

Описание к видео Marantz 2220B Restoration

Restoring old radios can be fun and rewarding, or it can be a dusty horror show. This one's a bit of both. The Ol' Marantz calls for recapping everything in the signal path, as well as the power supply. We replace a majority of the small-signal transistors, DeoxIT the potentiometers and switches, relamp the incandescent bulbs with LEDs and she even gets a new pair of kicks. Finally, the power amp board gets new caps, as well as bias and offset adjustment.
