KA-7002 help!

Kenwood-TRIO | Audiokarma Home Audio Stereo Discussion Forums - audiokarma.org
Howdy Folks,

Been battling to keep the left channel on. Lots and lots of D5. De-fluxed main power board. More D5, on everything, including me (ha ha, just a joke). Tried jumping PRE & MAIN, tried jumping up and down, tried religion ("Please God, let it work this time").

It is a BEAUTIFUL unit, very clean inside and out, and so well made it brings tears to my eyes every time I touch it. I will work to fix this problem until I die, if only to touch that extraordinary volume knob.

Now listen, I am a bear of Average Skill and Intelligence. I don't know how to use a scope, don't have a signal generator, sometimes leave the house without pants on. Any "simple" advice & troubleshooting procedures for common folk would be greatly appreciated. The seller has kindly offered to send me a schematic, which will probably only confuse me more but will make me look impressive to my wife as I ponder it (upside down, of course) over a Newcastle Brown.

To summarize: Unit extremely clean inside and out (like, maybe one piece of dust inside it). Left channel drops in and out with a tiny "tic" or "pop". Protection relay clicks reliably and I carefully cleaned relay contacts with clean paper. D5'd every single pot, switch, RCA MANY times over 2 weeks. Looked for obvious cracks, cold solder joints on boards. There is a ding in the upper right rear corner of the right side panel, maybe from UPS but maybe not as unit was extremely well-packed. I love this thing and I will not stop until it is working perfectly, even if I have to pay to have it done, buy another one, or contract TRIO to commence re-production of the 7002.

Cheers, and much thanks ahead of time for any and all advice you folks see fit to pass on. :yes:

Birchoak
