[AMRadio] Matching a 100 watt PA am to drive 833'S

[Don Moore R Moore]

I have a older BC 1F series gates transmitter.  I would like to do away
with the 845 driver tubes and drive the 833's with a 100 watt PA amp. 
Does anybody have any Ideas what I would need to match the amp to the
driver transformer of the 833's.
