This was random almost like did you hear that? kind of a thing. Volume was sitting on maybe 3 when I noticed this although I don't think the volume level has anything to do with it. What could this be? Is this sign of needing caps done? Any of you guys with experience with old amps please chime in.
Thanks

Sure could be. Could also be the tubes need replacing.
There are some really great amp techs in your area. I really like
Bruce Collins at Mission Amps down in Thornton. A great tube source is Fat Willie Whittaker (Lord Valve) at
NBS Electronics in Denver.
