20-Watt Circuit Salad AMP!

That would probably need a heatsink.. Plus it is a really big circuit with four transistors and a big IC. No to mention all the semiconductors are not the parts used in pedals, so all of those would need to be sourced for this circuit.

Let's just say that the request is noted :) If i was to draw this, i would probably do it as three different boards - one for power supply network, one for pramp and third for power amp.

Don't know as i haven't looked, but aren't there any slightly simpler 12V amp circuits available?

rooo: If you want to build yourself a nice practice amp, i'd suggest to check out G2 kit at musikding. Built that for myself and it sounds just great. Plus the 240ac coming from the wall didn't kill me :) English documentation is a bit dodgy, but still readable/understandable. That's less than 100€ per kit - and you'll get really nice 2W full tube amp :) You'll want to get the bottom plate for it though - that'll be something like 7€ more. That'll familiarize you with ac rectifying and transformers. I felt like a king when i finished it.

Hey, thanks for the response. No worries at all. I did not realize it would be that big and complicated! I'll check out that 2w amp you mentioned. Thanks!
