I am planning to use one of those 90-100 watt solid-state rigs to drive a
4-1000 amp project. From what I can gather it appears that to be able to take
full advantage of an all grounded-grid/ cathode driven 4-1000 tube ,the
driver should be able to supply about 150-200 watts of drive. It would seem
the best answer would be to build a buffer/driver stage using perhaps a
single or dual 811A tubes that could be driven with maybe 25-50 watts and
deliver 100-200 watts of drive to the 4-1000. I was wondering if anyone has
ever tried this or any suggestions? How about a pair of 811A's running class
A driving the 4-1000 cathode? Thanks for any ideas. 73 Todd Roberts WD4NGG .
