My manuals say max plate voltage on a 2E26 is 600 volts and should drop 
into a Ranger. I have thought of doing just that. Obviously we can *NOT* 
run the drive up as far as we would with a 6146 in there! I'm having an 
awful time with a DX-100. The power supplies are okay but with a pair of 
6146s in there the finals oscillate! It's somewhat of a mess from prior 
owners.

I dropped in a pair of 2E26s and put the plate supply on the low voltage 
supply which is giving me a little under 300 volts. Mine is CW only. I 
don't expect to operate in AM mode. I'm getting about 10 watts out and 
it tunes and plays nice. I am going to run it that way in the Stew with 
the high voltage rectifiers laying on the bench and clean up the rat's 
nest later when I have some other TX to use in it's place. It's quite 
likely the original poster can operate by dropping in the 2E26 and may 
also get some satisfaction using the low voltage supply. Caveat..on the 
DX 100 I have no plate current meter connection so I have to tune the 
plate for power out. If I recall..the Johnson has the metering resistors 
in the final cathode circuit so just set everything according to what a 
2E26 wants. I don't know what it will do to AM (and won't lose any sleep 
over that).
