Recently someone posted to the effect that in a tuned plate tuned grid oscillator, if the anode resonant frequency was lower than the grid resonant frequency, the tube would not oscillate. Did I catc

oscillator, if the anode resonant frequency was lower than the grid resonant frequency, the tube would not oscillate. Did I catch that right? And does this apply in a grounded grid oscillator as well

ORIGINAL MESSAGE: -- REPLY FOLLOWS -- Very interesting, Peter. That seems to support the original statement about oscillating depending on the C-G frequency being lower than A-G. Changing the subject

A 3-500Z's grid resonance is c. 88MHz. I know of no 3-500Z amplifier that has oscillated below 95MHz. R L MEASURES, AG6K. 805-386-3734 r@somis.org _______________________________________________ Amps
