Tony was a pleasure to work with and the tube socket came well packaged and undamaged. 144MHz GS35b High Power Amplifier by DL4MEA It uses a 2N6084 RF transistor, and will produce 50w output max. If you think you can run a GS35B at twice the output of the 8877 get ready for a failure! The GS35B does NOT have a 2500 plate dissipation as advertised to the ham community and extrapolated from the radar specs. its a pity it is now so damn expensive :-( To ensure robust longevity, personally I would not push a GS35B beyond circa 3 kV max on the plate?. Originally designed as power triode for UHF Radar applications it has a plate dissipation of about 1500W. The Linear Amplifier is produced by M+E Mechanics & Electronics Inc. I can get a fairly good match from 160 to 10 meters, but the matching is very poor on 6 meters. Triode Amplifier Control and Protection Please don’t start to build the Triode Board until you have read all of Sections 3–5. The amplifier is a push-pull design, using a dual-LDMOS device; by nature, this type of amplifier does a good job of suppressing even harmonics, but the odd harmonics are monsters, so be sure to use a good low pass filter. The socket to the right has my *Teflon® Chimney in place. This should deliver enough drive to be able to get the GS35b to it's dissipation limits. We also maintain Safety Stock, Low Levels and show you not only Current Inventory but Expected Inventory. While waiting for the boardhouse to make the printed circuit boards for my frequency synthesiser, ( see post on Mar 8, 2011 ), I reckoned I should have just enough time at long last to build the low noise 144MHz receiver RF preamplifier which I designed months ago, ( see post on June 16, 2010 for circuit schematic ).
