I've got a couple of tube amps that are little noisey at low volumes. How do you replace caps and filters? Are caps capacitors?
Thanks.

Well, if they’re that old, surely the filter caps (electrolytic) have been replaced at least once, that is, if the amps still work at all! The dielectric in electrolytics dries up over time rendering the cap incapable of holding a charge and 50 years is way too long even for the much better caps being made today. I’m not familiar with the Magnatones. Some old amps had these things that look like small, skinny aluminum cans sticking out of them that had the filter caps built-into them. Anyway, if you don’t think they’ve been replaced in a while then replacing them sure wouldn’t hurt. And like wrenhunter said, if you don’t know what you’re doing, take it to a pro – the voltages stored on the caps can be lethal!Bodhisan said:Flatpicker: Both amps happen to be Magnatone, one a Troubador from the late 50's, and the other a 10"er from the late 40's/early 50's.
