Dave: Use your ESR Meter and check the associated electrolytic, having the
EE Diploma will definitely assist it the rest of the quandary. Cheers.
FWIW Panasonic and Sony have been known for multiple 'ring cracks' in
their soldering, esp after a few months of thermal changes during nominal
operations, it's probable a good illuminated inspection mag lens will
assist?

Thanks, but I'm not asking the question, 'info' is the OP!
