The Overseas Only Kenwood Model KR 790

Ok, I took some shots of the Ebay switch which is the same as the one in the unit. Except the shaft is different. Butt he shafts are interchangeable. Also some shots of the Reverb Board. I'm going to swap out hose two diodes now. Just another shot in the dark. They did test good in circuit on diode check with my Fluke 8808A 6 digit DVM.

Here's the pic's

On the second last picture, look at C28. Is that cap installed backwards?

Yep..sharp eye's Leaker. I'm aloud one backwards cap out of the 20 I replaced L.O.L. on that board. Anyway It checked good even being in backwards. But I installed a new one and checked it with the LC103. Fired up the unit and still ...Audio in the off position ...Next click Mic only... that works...but no reverb...Light comes on ( That's what Board #13 & 14 run from the switch) ...Then next click is supposed to be Audio and reverb and Mix. I get the reverb light but totally nothing else. That cap that was in backwards is in the delay line control feed.

I'm still leaning towards that switch or a defect ( Cold Joint ...Broken trace) or something ???

Anyway tim for Lunch. Gives you time and me also to ponder WTF!!! L.O.L.
