    So a while back i bought several AO-44's (old Hammond organ reverb amps) off ebay for around $40 each. i looked up Paul Ruby's conversion that he did...
    ...and wow! 3 years later and i'm STILL in love with this one-knob, magical amp. is it sad that i can't find another amp that sounds this good? it's a clean machine (circa 12w) and boy does it handle pedals well.

    if you guys are looking for a great studio amp or just a simple project with GREAT results, pick up a AO-44 and do this quick rewiring!

    if i ever get around to it, i'll post some audio clips of this thing.

    The fact that it sounds so good confirms a local builder's mantra that the simpler the circuit, the better it sounds.

    Geez, and look at that NFB (guessing) that's being introduced at V2...wow....If I'm wrong about that, I sure would like to be straightened out on what is actually going on there.

    Very cool circuit.
