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.
