darn forgot to select "post reply" ... DUH!

I agree that they look to be paralleled, I also saw the corrosion and measured the traces from one end through every connection to the other end, all good. The only things that gave me trouble measuring were the switches themselves, which makes sense as mechanical devices exposed to water do not do well.

I'm looking for where I can get the replacement switches.

I also measured the resistors that are near what look to be hot spots on the board, they all match what they are supposed to be. Initially thought one or more of the resistors may have overheated and changed resistance, but they survived intact.

No issues with soldering, but I definitely feel the switches themselves are faulty.

Jack thank you very much for finding those switches (and offering to do some soldering for me!) but that's something I am very comfortable with (one of my oldest hobbies is tube audio, have been building/rebuilding stereo amplifiers and speakers since I was 13 ... I'm now 65)

One issue may be lining up the switches with the holes. as they will move a bit with just the two pins on the switch. I'll give it a shot!

Thanks again guys, I'll report back after new switches are in.
