RE: What tubes to use with this Interstage Transformers?

"Drive impedance would be at least 16x the Rp of the driver tube,"

Yes.

" input capacities of the following tube might be reduced by the same amount when reflected back to the driver"

The reactance of the capacitance of the output tube would be reduced by 16 times making it harder for the driver tube to drive that reactance.

Bottom line, to use a 1:4 interstage transformer one would need a driver stage with a very low output impedance and a ton of drive current.
