My guess is that one of the capacitors, C7, C8, C9 or C10 has changed value or opened up. C7 and C10 are 1500 pf, and I woul; /archives//html/TenTec/2008-11/msg00191.html (8,872 bytes)

My three Titan 425s drive to full power with 50 watts, and any modern 100W transceiver is reasonably happy with a 2:1 match at that power level. I typically drive them with; /archives//html/TenTec/2008-11/msg00192.html (8,320 bytes)
