Thank you all for the great suggestions!  I'm sure that I will be able to 
find just what I need now.

I've been having lots of fun playing with the push-pull VT-127As the last 
few evenings.

I've got the full 1800 volts on the plates now.  It will make just over 600 
watts out, but that's too much for plate-modulation, so I've been reducing 
the loading and got to just over 400 watts out.

At that setting, each tube is dissapating 70 watts and efficiency is 72%. 
Should be just right for AM.

Thanks again & 73,
Barrie, W7ALW
