Tube Mosfet Hybrid Headphone Amplifier Circuit

| 2008/11/08

The sound quality is pretty good I guess. The lamp used is 12AU7 Mosfet irf612 circuit, not too complicated. The supply is 12volt dc. As a follower of several YAHA amps based on the Fa-schmidt design and a Szekeres Mosfet, I wondered how the two would sound together. So I installed the schematic in TINA-TI,…
