I thought I would share the schematic for my "Pacemaker Champ." This project started as an old Pacemaker PM10 PA. I first based is roughly on the Kendrick Roughneck with a 6L6.

I then added a lot of switches for more sounds, and then finally an extra switchable gain stage from the Tone Frenzy Amp http://www.torresengineering.com/freplantomak.html
I used a 6AV6 for the extra gain stage as this is what the original amp had in it. You could certainly just use half a 12AX7.
