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
