Default HQ-145/Worth Recapping?

I repaired an HQ-145 that I picked up for a song. There was a bad RF choke
in it.
Anyway I decided not to touch the caps- why fix it if it aint broke and like
Colin I have a long list of radios to repair or build. It is one of the few
times I have never replaced the old PS caps in a restoration job.

I did not touch any discs, although I do replace all wax caps. I was
surprised that a spot check of resistors showed them all right on the money

Anyway 2 weeks after I get it all buttoned up the PS caps went. no damage
just a nice loud hum

ARRRGGH

Do like the radio

Bob,
I think someone was having a bad day...maybe
a pile of radios fell of the bench onto his foot. ;-)

The only danger of not replacing the filter caps is that
it'll short and fry your power transformer. Add an appropriate
size fuse, which is a good idea for any old radio anyway.
Replace the filter when it finally dies.
Thats what I usually do unless its a high end radio.

I have heard that there are very few electrolytic capacitors in this
machine, as most of them are ceramic disk. The only ones are in a can
on the chassis. If the radio is working well as original, would it be
better to just leave well enough alone? I always try to live by the
maxim: If it ain't broke.....
Thanks,
Bob Grimes
