Hi All , hope you are having a nice day
 Got a question for the hollow state guru's. I've just replaced
the powercord and fuse holder on said rig. (new cord is a 3 prong
with the ground connected to the chassis)
 I've had the rig for over a year and never messed with it until now.
I found it from a scrap yard in San Antonio (at .10/lb. a great deal)
and it appears someone had tried to sell it at a yard sale.
I have no idea how long it sat unused before I got it, and while
it does power up and work on most bands (10 and 6 were quiet)
it still has a few bugs in it. (the 6aq5 audio out is the neatest
shade of blue when running. gassy I know, I'm looking for a replacment)
So far 160 - 15 seem to pick up signals, and it does right nice on 80.
 The thing is, is that the electrolytic caps need time to reform.
 Proper procedure would be to reform them using a variac and 
stepping up the voltage every so often, or to flat out replace them.
 Problem, no replacements on hand, and the variacs I have are 
unaccessible. :< Fortunately the only electros are the main filter
(a 60u,40u,40u,40u jobber) and a 20u/25v. I'm not to concerned about the
paper caps, and everything else is variable, mica, or cd.
 Is there by any chance an alternative method to reforming 
old caps? Ie. maybe run it for 30 - 60min a day, and leave
it off the rest of the time.
 -=> Yours sincerely, Paul Williams KB5IVG <=-
... And now, to start gratituous EchoViolence...BOINGY! BOINGY! BOINGY!
