    Never get tired of looking at that Black Falcon!

    A pair of fixed bias 6V6's will put out anywhere from 15 to 25 watts.

    A pair of fixed bias 6L6's on the other hand will get you anywhere from 30 to 50 watts.

    Neil Young had his main 5E3 modded with bigger transformers and put in 6L6's (still in cathode bias I believe).

    To mod a normal 5E3 for 6L6's you'd need a bigger power transformer and possibly a bigger output transformer, then you'd need to change that shared power tube cathode resistor. Not too hard to do if you're building your own. This would turn a 5E3 into a sort of 5D8 tweed Twin (I built myself a 5D8 and it was AWESOME).

    Nice woodworking... I'm very jealous of your skills.

    Hey Johnny, what's a single el34 put out? I know it's plenty dang loud.

    I think about 10 watts.

    Heck, 5 watts is pretty dang loud :)

    When I got this Allen Chassis he told me it is 10 watts with the 6l6. I asked if there would be a problem if I tried a 6V6 or EL34. Nay on the 6V6 and he didn't think there would be a problem with the el-34 but he wasn't thinking in that direction. I might have to try it. I have a single Sovtek around here along with a Chinese KT-66 and an EH KT-88. I might have to try them!

    Depends on the circuit... especially the OT and the power tube's cathode resistor. It also depends on the power tube's socket wiring (most octal tubes are the same in the socket).

    Barring cathode biasing, as long as the power transformer can provide the proper voltage and enough current you only have to worry about the Output Transformer and trying to match impedance between the power tube's plate and the speaker impedance...
