• WARNING: Tube/Valve amplifiers use potentially LETHAL HIGH VOLTAGES.
    Building, troubleshooting and testing of these amplifiers should only be

Definitely NOT a Loftin-White!!

opinions on this circuit please.values etc.I've got a working version of this,just wondering if anyone out there can come up with operating points for it.My High voltage is 404v B+.

Um no, not really. I don't know how you expect to get anywhere near full swing from the driver.
Also, I don't know if you intended this to be balanced (PP), if not it'll have a lot of cross-talk at low frequencies, unless you regulate the cathode voltages.

What's the 2A3 plate resistors for?

Oh, and 12AU7 works a bit better than 6N7, though I suppose you have one or two on hand to use up.
