As I recall from the KT66 data sheet, the max value for fixed bias is 250k.However, the likely tubes to go in there are not the NOS MOV/Genelex...and so I would concur with the move that value to something more like 100k. That said, I would also contemplate lowering the matched 47k plate loads of the inverter...
The basic circuit is good, but change one thing and it is best to go and adjust the rest of the circuit as it is all what I would call it 'connected'.
