Well, one of the tubes has a white film around the glass near the teet shaped end of the tube. its right in the middle of little ones the two on the other side appear fine and the two big ones appear fine, just the one small one has that film, it looks to be the same brightness i guess.
jah, I'm ignan't but that's what you sunsaputs'r for.

Series resistance is not a leakage path; it's in series with the ideal capacitor, innit? Parallel resistance would be a leakage path around the capacitor.

In the equivalent schematic in at wikipeda leakage current component is indeed parallel with the cap, but would flow through the ESR which is shown in series with the cap.
 
agreed that the tube is losing it's vacum... dont see how that would make the amp run hot... it might smell some i suppose... cant say i've evr noticed one before... if you've got an old tube sitting around pop it in there... only caveate is ya dont want to run a 12ax as an 12at in the drive/phase invert position for any serious length of time... it would be ok for purposes of checking out though...
 
don't you have to switching something on the amp before you touch the tubes lest you get electrified? ergo unplugging it i already figured that out.
 
inbetween the silver and the stuff inside is where it went white. I will give it a wiggle. I think it sounds like a nice plain tube amp and takes my badmonkey and double muff quite well. The only thing that sounds like crap is the boost switch which really muddies up the sound quite badly, but the treble is awesome.

That is to say, unless you walk in with a Rickenbacker. :p

Oh, we work on Rick's, we just charge more for them as they take longer to work on. It's Muttley who won't work on them, but repair is his sideline business. I'm mainly a builder, but the shop is mostly a repair shop.
