>what is the maximum watts output in AM or FM mode for a cathode driven
>(grounded grid) 4-1000A tube whit 7,200 volts on the plate.
About 3000w.

4,000w of AM carrier requires a linear amplifier that makes 16,000 w PEP.
I would use a 4cx10,000D @ 8 - 9kV, 4A peak to do this. Drive
requirement is c. 150w PEP. Triodes like the 3cx10,000A7 requires c.
1100w drive. For 8000w of AM carrier, I would use a 4cx15,000A @ 10 -
11kV, 6A peak. Why do you need AM?
cheers, José.
