[NLRS] Looking for RF transformer

[Dr.Gerald Johnson]

Aw, just hook them together, no pad, no matching and let them live. The quarter 
wave of coax has a 20% bandwidth, and certainly would do the match just fine. 
The higher impedance load of the tube grid circuit (which may be tuned for 
frequency AND impedance match) will get really good power with no 
adjustments and just a little twiddle of the grid matching and tuning will raise the 
drive to the tube.

Tune that grid for maximum output from the driver. Likely you will find the tuning 
double humped because when its optimized for drive its hitting the tube too 
hard.
