Hey guys, sorry again for switching and thanks for trying to help!
It now works perfectly, my tone pot just didnt conduct from one side to the middle

Not sure why you switched threads, but whatever... It's possible that you've built an oscillator. That requires positive feedback, which can present itself in some surprising ways. Typically, low frequency oscillations are caused by coupling through the power supply. Do you see the B+ bouncing in t...

Hey guys, ive been trying to build this thing, but it just doesnt want to do anything, ive already fixed some mistakes but im at a point where i just have no clue what my problem could be anymore, can someone of you who also build one glance over my layout if he finds something that i missed? I woul...

Thanks guys! Mightve been a little bit of a hard first amp build, but hey, im learning tons of stuff so thats cool!

Thanks so much for helping, i seem to have found the problem, i think. C15 does normaly carry the signal to C104 with ~4VAC but over C104 it goes down to 0,5VAC, that probably shouldnt be the case right? Ive tried resoldering it and checked it with the DMM unsoldered and it showed up normally, can i...

If you're working off a known good layout/schematic, and modify it, it's best to revert to the known design, and make sure that works. If it does, try the mod again, but make sure you write up a schematic and illustrate the mod so that someone can double check the attempted mod. Also pictures of yo...

Ive also tried injecting a signal and if its loud enough (tried it with a headphone amp) it does amplify stuff, doesnt really matter where i inject, even at the input and all tube grids, just has to be at like half volume of the headphone amp. Any ideas?

Hey Guys! First post here, just been lurking for a week or two. Thing is, ive been wanting to learn some new Stuff and have a new DIY Project, so ive been trying to learn some electronics and build myself an amp. Im done now, but it just wouldnt make a Sound. Ive errorchecked against Matecs schemati...
