> How much drive you need? Or, what are you wanting to drive?

I'm working on two rigs right now.  Number one is a push-pull pair of 
VT-127As, which are an early radar tube.  They have the plate of a 100TL, 
and the grid and filament of a 250TL.

It's possible that I'll need up to 75 watts of drive there.

I'm also slowly rebuilding a push-pull pair of 450TLs that I first built in 
the early 1990s.  It was driven by a 32V3, both RF and audio, and worked 
very well.  However, due to the "old style" of construction, with very 
little shielding, it was an enormous RFI/TVI generator.

I'm sure I'll need at least 120 wattas to drive that rig, but that's a ways 
down the road.  I could build a buffer stage there.
