Off-topic Question

You need enough filament voltage to make the rectifiers work.
Otherwise you need to control the voltage to limit the current flow
through the caps. If you have the old fashioned type of cap checker
with a variable DC voltage you could use that. Pull all the tubes and
step the voltage up each time the milliamps drop to near zero as
shown by the tester showing 'Good'. Don't exceed the rated voltage on
the caps.

Or, pull the other tubes (not the rectifier), add a high value / high
wattage resistor in series to limit the current to a few milliamps
and just run it until the DC voltage drop over the resistor nears
zero.

I've come into posession of two vintage Atwater Kent radios, neither
have been turned on for at least twenty years.  I'm assuming, at the
very least, that they need their electrolytics reformed, but I've
never done this.  Anyone know the procedure or a web source that I
can go to?  Also, are there any other things I should look out for in
bringing these back to life?  To quote your average eB*y seller, they
worked the last time they were turned on. These belonged to my father
and they're very special to me, so I don't want to screw this up.
Thanks in advance.
