• WARNING: Tube/Valve amplifiers use potentially LETHAL HIGH VOLTAGES.
    Building, troubleshooting and testing of these amplifiers should only be
    performed by someone who is thoroughly familiar with
    the safety precautions around high voltages.

Just an interesting link

Yup, that's an OTL (Output TransformerLess amplifier). Yes, such a thing is possible, and yes, it completely removes the output transformer.
I've seen that design, and I like the looks of it, but the 6C33 tube costs more than I can afford at the moment.
It's not difficult to simplify it even further; you really only need one tube up front connected as a differential.
Another good tube for OTL designs is the 6AS7--another power triode. It's not as high-powered as the 6C33, but it's also cheaper.
I've got an OTL design I've been working on for a while (in between other projects). When (yeah, yeah, Grey, we've heard this before) I get the silly thing going properly, I'll start a thread.
