Hi Bob;
That's correct, the 3CX1500A7 and D7 are completely different tubes. My
remarks were from experience with the 3CX1500A7, the 8877. I don't know
anything about the D7. If the tube is a 3CX, then it's a Triode (unless the
coding has changed).
If you're interested, you might have a look on
Hi;
40-50 ma of grid current should get you about 1500 W out. Don't over drive
the tube and it will last for years and years.
Eimac tests the 8877 key down at 30 MHz , 3kw for hours before it's sold.
It's a very good tube.

I've done the same with many rigs. I currently use a K2 and Omni VI. The TT

If you do, with alcohol, be sure not to use Completely Denatured Alcohol. It

Be careful. I'm sure your boards will be fine if you use good solder and
