So here's the short version:
I have 3 things on my to-do list. I want to make a ribbon-mic worthy of being the center-piece of my mic collection, build a custom guitar tube-amp as good as an expensive Vox but small enough to carry, and most importantly I want to build a pre-amp like the S610 (UA) or the M5 (Avalon).
The guitar amp schematics are everywhere but I can't find schematics for either of these tube pre-amps anywhere.
I've never built one before but I have my cousin's assistance (he can build anything, he's like McGyver lol) so I'm going for the best because I have no use for anything less.
Does anyone know where I can find the schematics for either of these?
Any advice to help me in building this for the first time?
