Title: Need a simple tube circuit
Post by: Fossilshark on May 22, 2016, 02:46:51 PM

Im looking for a simple tube circuit for a guitar amp. I recently had a chance to play on a marshall 40 watt half stack and i instantlt fell in love. My favorite thing about it was the distortion i was getting when i turned the gain up, it was like variable distortion! I was wondering if i could find a circuit that had something like that where when the gain starts to go about halfway it starts to overdrive the tubes. I only need about 5 to 10 watts (special idea i have ill share in another thread) of power for this amp. Any ideas?

Sure, build the preamp from that amp you like, then wed it to a tiny little power amp, say one from a Champ.

Thanks for the schematics but that looks a little too complicated for me. Im going to use a single 12ax7 tube preamp for starters

You need two, sorry.
Check the schematics I suggested in your other post.
