Hmmm, there is quite a significant increase in the output power of this
particular amp (AMERITRON AL-1200) between 85 watts of drive and 100 watts of
drive, so it seems that the tube continues to make power from 85-100 watts of
drive. At that point (100 watts of drive) the grid current is about half of the
maximum permissible. I contend that the amp would continue to make power
right up to the maximum permissible drive level of 130 watts.
quote from Ameritron AL-1200 operating manual "maximum permissible drive
power 130 watts"
Ron, hook that baby up to your FT-1000 and run it up with 130 watts and let
us know what it does.
