EL84 PP amplifier...



Published
EL84 amplifier, 6n2p pre amp with FET phase splitter and FET buffer before the James tone stack. no feedback in this model. The transformer is recycled from a vintage radio and the OP transformer is for a princeton reverb. The goal was to make a cheap Uke amp so needed to be fairly clean and that could also work for a standard guitar so can get a little dirty.

The PSU is regulated to 280V the IRF840 is used in all three locations.
