Fran, try taking a look at the backside of the board, if you can lift it slightly and put a mirror underneath. The traces may even be gold-plated. I can see from the top how old-school curvy they are - all made with love by hand... Pure beauty!

Very nice "old school" construction. My experience with electrolytic caps of that vintage has been 100% positive; hardly ever seen them fail. I'd be willing to bet that it will work without any repair necessary.

Love the old boards Fran - quality craftsmanship, no robots ;-) Nice S&T cheers!

Quincy is pronounced "quin-see" locally in MA.
