In Reply to: RE: Any links to Berning's published curves?... posted by garymuffley on November 15, 2021 at 07:55:31
...Berning's website looking for the curves for g2 drive. Didn't find any but I did find Berning's patent for g2 drive #3,995,226 dated Nov. 30, 1976. Primary benefits/characteristics cited are increased reliability at high anode voltage, cooler operation and "..linear, highly efficient operation resulting in relatively high power output..". Nowhere is triode or triode-like operating characteristics mentioned. The circuit is as I described earlier where g1 is strapped to the cathode and drive applied to g2. Read it for yourself at the link above. Seems to be an interesting error in the second paragraph of "BACKGROUND OF THE INVENTION".
Follow Ups:
Diodes?
I assume the patent writer intended to use "tetrode" or "beam tetrode" where diode shows up. OTOH, Berning is innovative and maybe he envisioned an output config. somehow using diodes instead of traditional control grid devices. Who knows?...David Berning knows!
