However, when I actually built the circuit, the output was very clean and about 21/2 watts. I'm thinking of using a Hammond 290CX which according to their sheet is 650v 180mA, so that should be a pretty direct replacement, it would just run a little cooler, right? The output transformer recommended was a 5K primary unit, a standard value. So that's 700v across, supplying up to 150mA. The Mojotone transformer has 350v x2 for the first secondary wiring, right? So that's 700v across, supplying up to 150mA. ClassicTone # 40-18110, Fender 5F1 Tweed Champ Style Output Transformer, 4 Ohms 40-18110 $31.07.
