• 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.

Hammond 1650 experience?

Got new 1650W’s in this build. Williamson topology, and it’s low frequency stable. 200 watts, 300 on peak before voltage sag. Can’t complain about the HF response, either - but I can’t hear a thing above 14k. Didn’t have any unusual problems with HF stability which would indicate transformer problems.
