• WARNING: Tube/Valve amplifiers use potentially LETHAL HIGH VOLTAGES.
    Building, troubleshooting and testing of these amplifiers should only be
    performed by someone who is thoroughly familiar with
    the safety precautions around high voltages.

The cathode FeedBack in Push-Pull amp

Here I am:


This is the little brother of the previous project and the name stands for "Tube amplifier for the people".

The designer is Bartolomeo Aloia, a real guru, maybe he can sell You the kit and in this case can give You full assistance.

PS 4 tubes for a PP is really the minimum, not maximum. Note that V1 and V2 are a 12AX7 with two paralleled section to increase gm.
