Picked this up at the Great Plains Audio Fest in Tulsa, OK this weekend. (I'll post another thread later with event photos)

My first SEP amp (Single Ended Pentode), running a pair of 6197/6CL6 power pentodes, and a 5Y3 full-wave rectifier.

    Sides and power tranny are matching 'blues'.

    Only 1 capacitor and bias resistor in the signal path. The front mounted gain pot is wired directly from the rca inputs, to the power tubes.

    Telefunken output trannies, output is 2.2 - 2.5 wpc and it loves low impedance loads.

    Cheers,
    Russ

    I'd love to hear your Cains on it too!

    Now, time to build some 8ft tall open-baffle jobs with some of these old Alnico drivers I have laying around.

    Cheers,

    Russ,

    Whose design is it? Is the circuit layout available online? Looks like a really nice prospect for a DIY project.

    Simple and sweet looking...

    What is it, about an 8" square footprint?

    Awesome! The rectifier tube looks sweet. It looks like a 300B (my fav looking tube). Guts is nice too. Talk about KISS. Can't wait to hear what you think of them.

    Yeah, about 8" square.

    It's just a coke-bottle 5Y3 vs the standard versions, which aren't much taller than the 6197's. I put em in because they look cool, I've never heard a difference in sound.

    Cheers,
