400 mfd electrolytics with radial leads. Wrap the leads back over
the body not touching kind of making a barber poll out of
it. 200volt supply on the bench and when the new kid comes in the
door you pick it up by one end and holler catch as you pitch it to him.
You learned to duck and cover really quick instead of catching ;-)
How did we survive anyway???

BTW, do be careful when mucking about with power packs. if something
shorts out on a fully charged pack, it can knock a person off their
feet or worse.
If they're really old school electronics, (nothing really hi tech),
and you have access to an old variac, you could put a low voltage
against them for a few hours. Say less than 20 VAC in, to let the
caps reform, Then ramp up the input voltage to see how they react.
I'll bet they're dried out however.
Getting hot. Yea, when they let go you get nasty goo all over
everything inside, I've never seen one explode, but the stuff is
corrosive, not as bad as a dry cell, but still not so good for the
health of the wiring.
