Hey all, I've got a 2002 Hot Rod Deluxe (that I've posted questions about before), and I recently had some weird problems with it. The overdrive channel has been dead for roughly a year (really low volume, no good distortion even with everything on full) but the clean channel worked great so I just used pedals. A couple weeks ago, the clean channel also died and wouldn't get to an acceptable volume at all. Right before a gig too, of course Plugging straight into the power amp worked fine and the tubes weren't to blame because I replaced them all and still had the problem. Earlier when the dirty channel died, I replaced one of the relays (K2 I think) based on the advice of one obscure sentence on the hotroddiy website, and the dirty channel worked again for a few hours and then died again, so I gave up and just stuck with the clean channel. This time, on a hunch, I replaced both of the switching relays in the amp, and whaddaya know, both the clean channel AND the dirty channel work perfectly again! I've played it for a few hours without problems but will be doing some extensive testing in the next few days. So after that novel-length backstory, here's the question: My amp has gone through three replacement relays now, so did I solve the problem or am I just treating the symptoms? Before I owned the amp, the two resistors that feed the relays - and that commonly get burned out on HRDx boards - got pulled off the board, replaced with beefy higher-wattage ones, and bolted to the metal chassis for heat dissipation. Whoever did the work did a really nice job of it too. So that common problem is dealt with, but I still wonder if somehow the relays are getting too much voltage or if something else is causing problems. Do you think I'm at risk of blowing out more relays because the rectifier or one of the other transformers is going bad or something?
