{Collins} AM Modulators



Good morning to all. I have a technical question for the engineering background members that I am unable to find the answer for. If we examine the Eimac data sheet for the 4-125A tube used as a AM modulator  in Class AB1 we find that two tubes in push pull at 2500 volts on the plates will produce 330 watts output and exhibit a plate to plate load of 20,300 ohms. If we connect four tubes in push pull parallel the output would increase to 660 watts. Will the plate to plate load resistance be cut to 20,300/2 or 10,150 ohms???  Thanks for any help you can furnish. 73 Jerry K9GOZ
