Kenwood L-07MII Power Amplifier Repair and Restoration

Being one of my biggest restoration jobs to date, this beautiful pair of Kenwood L-07MII amplifiers needed a lot of work. Virtually no stone was left unturned. Everything from rear I/O connector replacement to the replacement of almost every capacitor. Also addressed were the issues pertaining to the stability of the high speed circuit. Specialized care and maintenance like this is seldom found, and is never cheap. This job took hours and hours, and I tried my best to condense what was done down into a video for YouTube.
