Had a request for a Total Rework of a 4000t, including recap, power supply rebuild/modification, and a remote volume kit. It was a bitch. But, it sounds nice, and it works pretty cool. The rework of the volume knob to accept the IR receiver was a trick and a half. He was fine if I wanted to drill into the faceplate, but I can't do that to a 40 year old unit with irreplaceable faces. Just got to detail, and ship.
