    intended as preamp in my next rig, so no point in building 50watter and attenuating before fx's and poweramp. output tube is a 12au7 in cathode biased push pull. output transformer is a tiny toroid. I've used those before in similar builds.
    basicly its a 50watt jmp with a different powersuply and output. if I change my mind, I'll just mount octal sockets, and rebuild the powersupply and add a 50watt optx
    I dont need the bias supply, but built it anyway. the 50watt transformer I have laying around doesnt have a centre tap, so I reconfigured it like a 900 with class x capasitor

    Cool!
    I dig your concept!
    Have you tried it any cabinets?
    I played the 1w ann. Marshall on a 4x12. It got balls. More headroom than expected!
