Tube Amp Archive

Well, you asked me to measure the voltage... **************** xtian: Yeah, that's pushing it. Anything over a few tens of millivolts will get your volume pot scratchin'. So throw in a 12AY when you get one, and that might also solve your "too sensitive" problem as well. **************** xtian had ex...

Yes, I understand it... But for 5E3 in that case I'll need 4 wires from connector's to the tube. It's sounding OK now and I have only two wires... It will be case in my next build - Dumble clone... (I'm just in love with that amp and I want it for myself...) Here is some pictures of this elegant 5E3...

I took your advice, and do the following ... moved 68K resistors to the input connectors, coaxial cable signal led to the first tube. With the coaxial cable I brought signal to the tone control, and from the tone control coaxial cable to the second tube... (removed not used turets from the board...)...

On DC it says 0.362 V...

well, it can be a problem... My tube is OK, but it is 12ax7, not 12ay7... In my previous 5e3 12ax7 works fine... I do not have 12ay7 now so I can't test it now...

I need some help, this is my third 5E3 amp, and whit this one I have a problem... Amplifier is to much sensitive, and I have schretching pots on guitar when amp is on high power. It is too loud, and all voltages are correct.
