Started out with blown TR43 last final before antenna. Replaced TR43. TR44 Driver was good and TR46 first final was good. I replaced all three for good measure. TR45 pre driver checked good. TR46 RF Buffer Amp checked good. Although all voltages for finals and drivers are not listed I was able to check all voltages they seemed good and was able to adjust gate voltage as per. CB Tricks Galaxy 33 HP. So when the mic is keyed TX light changes but no output. I get a bit more ripple on sope if touching the collector of pre driver (TR45). What have I missed?
