I have access to an "SB-226" locally which I have studied it and
measured the component values in detail ( nothing magical there)
I dont have the same Plate tune cap (exactly) but I am very close
I tried a coil which was a duplicate to King Conversion coil and I
ended up using a section of the original SB-220 tank ..there was no
difference
I have made some progress this morning ( up to 750 watts in SSB mode) by
"strapping" some additional grounds. This is a very old 220 and stored
in not the best environment (power transformer is rusty as an example)
This afternoon I plan on finding as many ground connections as possible
and "clean" them up, then going to do the hard ground of the grids mods

Dave,
Lou, W1QJ, King Conversions, did my "SB-226" conversion. It's good for
more than 600W out for sure ;-)
Very happy with Lou and his work. I am not sure if he'd be willing to share
some of his secrets, (or paying some amount for consultation might be fair)
or you could just arrange for him to finish the job for you.
