Sounds like your tubes have some heater-cathode leakage. The solution is to use a different tube.

Well, maybe he meant that it had no microphonics when it was not plugged into an amp.
This is a circa 1943 RCA 6AS7G. I noticed people online doing things like baking them in the oven to 'dry out' the bakelite base in case of shorting that way. I presume the heat generated while being used would cause that moisture to flee the base though. I'm going to test the 'bulb' from the base to make sure it's not loose tonight. I'd love for it to quiet down because I really like the way it sounds. I need to befriend someone locally with a tube tester and the knowledge required to use it.
does anyone know what this amp is worth fully assembled & built without the upgrade kit?
Is it sold as assembled or only diy kit ?
