<If it is pure AB1, never driven into grid current, and if the capacitor
and circuitry have zero leakage <then I don't see why not! . Won't work for the reason the resistor from the grid of a vacuum tube to ground was called the "grid leak" back in the first days of tube type receivers (yes, I was there). Some of the electrons ejected from the filament will strike and become attached to the grid structure, and if not " leaked" off, will make the grid negative enough to cut off the tube. Look in the old RCA receiving tube maunal--you will find the maxiimum value of the grid resistor listed for each tube type. 72 Paul W5DM _______________________________________________ Amps mailing list Amps@contesting.com http://lists.contesting.com/mailman/listinfo/amps |
