ecp & Pickett Furniture Guitar Amplifier Prototype


This is another partnership with Pickett Furniture. The circuit uses a pretty standard 12AX7 based gain stage. It then uses a FET source follower into a 1:1 transformer as a phase splitter, and a fixed bias push-pull EL84 triode output stage for a couple of watts of power. Case is solid walnut. Speaker is AlNiCo from Weber.
