Valve Crystal Oscillator Grid Current

[John M0GLN]

Thanks for posting that explanation Lawrence although it's getting a bit too advanced for me, I'm still just a little surprised that as 40mA is flowing through the lamp and crystal that the control grid can either source or sink a current level which is the more or less the rated anode current of that particular valve. I think I'll just accept that it happens and that's that.

Thanks

John
