"It worked until it didn't" Famous last lines, eh?
What I am looking for, is perhaps guidance to another forum (or even a member here), that is knowledgeable about diagnosing what seems to be a simple PCB situation. I'm handy with a DVOM, however there are no schematics available apparently for this rudimentary metal detector I have owned and very seldom used.
I can randomly join another electronic forum, but I thought I would entertain forum suggestions here for DIY electronic types.
