Jim,
Several people have accomplished modulated grid
operation with a vttc. Sue Gaeta has a schematic on
her page. Also, a through search through the Pupman
archives will reaveal some stuff if I remember
correctly. You also might want to check that web site
that attempts to unify many of the vttc projects on
the internet (can't quite remember what it's called, I
have the link on another pc in another room).
I would love to do this with a vttc, but the fact is,
it is just so much more flexible and easier to do with
an sstc. Use a good PWM chip and it's pretty much
plug and play. It's looking quite like I'll be
playing with that, long before I'm planing any
records/cd's through my 833A system. I basically have
all the parts for my next couple of SSTC
projects...everything except for the 30awg magnet
wire.
