Thanks for the great info.  I do have an old Radio Handbook by Orr which has
some great information in it.
I basically descided on grid modulation as Dave Trimmel has successfully
accomplished this already with his
dual 833A tube.  Also, Sue Gaeta did have a nice audio modulated VTTC, but
she was running at lower power using
high-side modulation on the plate supply itself.  You are correct, that this
type of modulation with a dual 833A putting out 2-3kW would require a pretty
big modulation circuit on the high side.
