I wanna build one of these, but i just can't find these tubes here in Brazil for a reasonable price... So i'll build one with some tubes i got for cheap: a 6BZ7 Twin-Triode on the preamp and a 6AS5 Pentode on the power section.
I'll try using a 30v+30v transformer to get 120V (via a voltage doubler), 60V and 30V, so that i can use a 3-way switch i have here to change the output power (120v = 2w; 60v = 1w; 30v = 1/2w).

Based on the idea of the Sopht amps, but the circuit is mostly my design. Thanks for your interest!
