You know, that's a good insight.
It would be nice to be able to use the plate B+ for both V1 and 
V2, but of course V2 is feeding RF to the original 12SK7's plate 
circuit so if one tries to put them both on the same 
buss.....hmmmmm....
Maybe a paralell resistor across the screen dropper to boost V1's 
plate voltage?  I could live with that change.
