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.

Apsara Amplifier

All of these little stories seem to be the same – I tried to build some circuit, it went badly, and them some little change made it great. This one is no different.
