Hello bob,
Good to hear that you ordered some craig products and cleaning those switches will help the set and I know what you mean about "like finding a needle in a haystack "

I remember when my Repairshop was going full steam back in the 90s a customer brought in a Jcpenny tv wow I did finally find the needle using heat and freeze spray it was a zener diode .

Good luck and we are here to aid you in your adventures of repairing old radios.

Sincerely Richard
