I think someone else on this thread suggested connecting the 6v6's 2nd grid straight to HT.

The 6v6's 2nd grid resistor used to be the 2nd pot, but then i bodged in a fixer resistor (the one in the pic that looks like a bodge with bare wires wrapped round the terminals). However after more advice i bypassed it with wire.

In all my amps i used a 22k with a 20uf cap to ground for the 6v6's grid supply.

I'll see what happens when i get the o/p transformer. Then i can make refinments.

I think maybe hthe best option would be to have a pot for the 6v6's grid vltage, with a cap to round as well for decoupling. that would amke a volume control...
