Hi John,

Thanks for your concern about that. I already noticed that I can't just 
pull that line to ground as it's wired now. That is, pulling the 
junction of those two resistors to ground looks pretty dicey to me too. 
I'm thinking more of isolating the screens of those three tubes so they 
can be pulled to ground without much influencing the resistors in the 
original circuit. A reversal would just cut out the added parts and 
reconnect the screens as original. Achieving QSK is worth the effort to 
me. YMMV.
