Picked up this sweet Kenwood KR-4070 stereo receiver for $50 a bit ago. After a little AM & FM RF/IF alignment and one meter lamp replacement, it works perfectly for an almost 50 year old receiver. It's only 40w rms per channel but it sounds great. It still has the original problematic output transistors and the original dial indicator lamps so I believe it is a fairly low hour unit.

An update (finally) bench testing an AIMS 36volt 5000watt inverter with a (light) load for the next 12 hours or so.
The Nakamichi BX-300 cassette deck came back AGAIN! I determined that it was indeed the loading motor commuitator to brush connection issue. Video should be up in a few days, when I have time to edit it. Thank you everyone for your patience.

Working on a Definitive Technology Powerfield Trinity subwoofer. It has had a complete recap and still needs 4 output FETs and FET driver ICs. Hopefully the customer approves the estimate.
