Hi Ralph, Probably the easiest way to do this is two 6146s in parallel with the plate voltage up near 750 volts or 3 at near 600 volts and use the rest of the parameters from the tube manual. It would be simple to do with more common available parts. The Heath DX 100 or Apache would be a good design for the two tube kind of thing or the Johnson Valiant for the 3 tube version.
Modulate them with 6146s and you are off to the races. There are other modulator tubes out there, but they can be more expensive and finding a modulation transformer to match them is a little more difficult. This is a fun project and I hope you have very good luck finding the parts.
