I found that by making a small 4:1 balun and loading the grid with a
resistor I could drive it with no grid tuning. Simplifies the amp.

Hi Gary.  You may recall that I built one of these for the 6HF5 amp that I
built for my 20A.  I worked great on 75m but not on 20m.  I may have not
had the right core.  I just don't know.

Anyway, I want to try again, this time to convert a set of B&W 813s (the
L1000A, I think) from GG to grid driven.  I could then use the 20A to drive
these, and I could also plate modulate them for AM.  That is the grand plan
anyway.  Do you see any problems with my thinking?  

73, Lynn.
