Hi All. I just did something real stupid by forgetting that my antenna was grounded and transmit my Argo into a dead short. Now the power meter just slightly wiggles at a power setting what once was
Scott, I blew the final transistors on the previous model, the 509. Sounds like you know what you are doing but I'm going to throw in something anyway that we all know and keep trying to forget: "IF

You want a matched pair. Push-pull PA stages usually don't bias the transistors independently, and setting the bias only sets the DC operating point, not the gain which varies from differences in the
Scott, Contact TT and see if they have the transistors you need, and ask them for any substitutions. Hopefully, you only blew an ALC diode. 73 and GL, Stuart Rohre ___________________________________
Thanks for the replies fellas. I disassembled the amp section and did some troubleshooting and found that one of the finals is blown. It required the base of each transistor to be lifted and tested w
