Valve Crystal Oscillator Grid Current

[John M0GLN]

Thanks for that Al, I'm glad you did the maths not me, I hope I didn't put anyone to too much trouble on this as it is not a circuit I chose to use in the end.
I've just finished building an 80M AM transmitter with a 6AG7 driving an 807 final, after looking at a lot of ideas on the web I ended up with the 6AG7 in a 'electron coupled oscillator' circuit, this works very well with miniature HC49 crystals providing more than enough drive for the 807.
The modulator is a 'Reference Shift Modulator' taken from June 1956 issue of 'CQ'.

Thanks

John
