At least in radio repair of old equipment,,,, old electrolytic caps cause all sorts of issues. Most of the guys doing restoration do a total remove/replace on them. In my opinion,,, I think that's a little extreme,,, but then having one fail after all the other work is done is also a PITA.

Hi friends, Now that I have enough hobby time having quit my job two weeks before the apocalypse, I'm interested in poking at my Kennedy 9800 tape controller project. I bought the tape unit in Q3 2017 and the seller said they had powered it up and nothing seemed awry. I have not powered it up and reading about old electrolytic cap issues I'm curious if I should do anything beyond replace any obviously leaking/ruptured capacitors. IIRC people have used a variac to gradually bring the power supply up to operating voltage and somewhat refresh the capacitors - is this a thing? Is this advisable? Any help is appreciated! -- Anders Nelson www.erogear.com
