Running in Class A2, 350 Volts @ 100 mA, it will put out comfortably 10 Watts SE. Circuit using C3G (triode mode) drive KT66 cathode follower directly coupled to 808. Transformer is limited to 100mA, or I would have push the tube more to get close to 15W. Power supply is more complicated than SE circuit, using two regulators, for output and driver."
