That's several useful valves then, thanks for the info,
Now we need to declare which are completely useless for anything else. That will free up some space in my shed.
And anyone got any circuits to use the better ones in?
That idea of voltage double for filaments is a good one, I was thinking of using cheap Chinese Buck Boost modules, they are available now for 99p unless anyone knows better.
