    I would like to know as well...... The 3-6146's (also modulated by 2PP-6146's) in my Viking Valiant easily puts out 150W of unmodulated carrier at about 350ma.

    No, it just sits there in the storage room to remind me what I have to do.
    .....but any day soon.....I will:)

    The first thing I will do is building a proper power supply.

    This is my Genemotor and modulator. Is it similar to yours?

    Genemotor spec.
    It says +600V and 225V witch I suppose is plate and screen voltage.
    Is this what I should aim for when I design my own psu?

    It is interesting to note how much SSB and hybrid circuitry improved efficiency.

    The Aerocom rig requires at least 25 A at 28V, but my Collins 618T-3 runs quite comfortably
    off a 30A supply with 400 W PEP two-tone excitation...

    Hope to get the antenna coupler working for a QSO some day...

    The 618T is a really nice rig! I have a lot of hours operating one of those! Sure wish it had LSB! (It actually "had" it, they just didn't let us select it!!)

    I'd love to have one now!!
