This is correct and I overlooked the fact that when I am using a swr analyzer on an amplifier input I know the grid impedance and put a resistor string from the grid to ground to simulate the presence of the tube. I guess all of the linear amplifiers now have the grids grounded and you drive the cathode. I apologize for the mistake. 73 Rob K5UJ _______________________________________________ Amps mailing list Amps@contesting.com http://lists.contesting.com/mailman/listinfo/amps |
