If a capacitor has gone dry, wouldn't there be a clue like bulging tops,
leaking brown crud, and a horrible smell when they get hot?

you can make a quick esr analog meter to check all your caps
the small capacitor next to the uc3842 aways fails to an esr meter
even a cheap build from scratch analog one.

my web site contains easy and more complex esr meter to build yourself
