One thing to remember about "big"  RF power tubes; they take lots of
filament power too!  Also, filament voltage is quite critical if you are
pushing them +/- 5% is pretty typical.  Running too low will reduce
output and too high will reduce tube life.  Moral - know your tube specs
and adhere to them.
