HQ-145/Worth Recapping?
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.

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 -- |

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 -- Carl WA1KPD Visit My Boatanchor Collection at http://home.comcast.net/~chnord/wa1kpd.html "Steve" wrote in message ...
