Re: how to recondition capacitors ?

Thanks,

once I run that thru the charging process, how can you tell if it is
still good enough for use in a power supply ?

and darn, all my power resistors are less than 100 ohms. I'll have
to get some parts.

In checking, I wound up with 3 10,00uF, a 15,000 and a 22,000 uF not
bad for striping old boxes.

I wish some of the power supply stuff was rated for more than 6 amps
though. nice input filters on the old boxes.
