Leanne W1WXS You never saw the big 4-1000A amp I got from JD Black, WA4DVK in Orangeburg, did you? It was in a WW2 Navy transmitter cabinet 24" wide and 7' high. Pole pig hooked up backwards for 7200VDC, cut back to 6KV with a 230VAC 30A variac beast on the primary, home brew filament transformer, regulated screen power supply for stability, running COMMON CATHODE! Input was a 50 ohm, 100W dummy load into a drive potentiometer so you could turn the drive back to where the tubes were designed to operate. No tuned input necessary, it was a dummy load for the rig. Output was a shunt-fed Pi network with huge rotary inductor with nice turns counter, 500pF, 30KV vacuum variable input and broadcast air variable dual ganged output cap both with nice vernier, calibrated dials for fast band changing. Huge broadcast transmitter meters across the top, screen-shielded window to impress the shack guests looking in over the pair of 4-1000A graphite Amperex finals. I brought a piece of melted RG-8 to a club meeting one night. "Somethin' ain't right!", I told 'em...(c; Great fun on 75M on a cold winter night. The little Heath HW-100 transceiver and a coaxial antenna changeover relay and we're in business...(c; Run about 20W into it and you'd see 6KV on one meter and nearly 1A on the plate meter. That's about a kilowatt, right?....Right! In Sumter, my neighbor's hall light was resonant around 3900 Khz. It followed the SSB modulation, lighting up quite brightly...(c; POWER is our FRIEND.... |

Found a picture of me in my sailor suit when I was an ET3 back in '65. Nice lookin' kid, but that was FORTY YEARS AGO! How awful.... |

Of course we used Comnav electronics and motor driver. (new mercury contactors are rare and expensive!) Lynn |
