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!
