Valve Crystal Oscillator Grid Current

[AlanBeckett]

My figures above should have said they were for Cga, which is where the Current is supposed to be flowing - sorry

The Cgk Figures are:-
6F6 6.5pF
ECC81 2.3pF
EF91 7pF

Still tiny.

I'll have to ponder on Inductve effects, but I'm still confused.

What we need is a really old Crystal so Al can do his experiment again.
