Filter capacitor checking/reforming is a good idea on older equipment that
has been unused for a number of years. I do it with a  "magic eye" vintage
capacitor checker. The type that has a leakage checker feature. The voltage
is current limited that keeps the cap from overheating. Connect the
capacitor and set the check voltage to the cap voltage rating. Leave it on
and wait until the eye opens. It may take hours. You can down range the
voltage switch temporally to see progression of reforming.

Person me please.  I thought this would be a good group of people to ask
this particular question of: I have some electronic and computing equipment
that I want to safely power up. I'd like to use a variable transformer. Can
anyone recommend a particular model to buy?

Thanks in advance. 

73,
Paul
