I have a gen 1 FT-817.? Recently replaced the finals board (had very low power on TX all bands).? Incidentally the board is still available from Yaesu for $24.? P/N CB1333004.
?
I thought I had the problems solved, however now I have discovered no TX power on 2M band.? Other bands are fine.? ?I plan to dig in the diode issue next.? Has anyone found a video or guide to assist with this repair?? I've looked around the web and not much out there for this specific issue.? ?Looking for any high res photos of the PCB and the diodes.? I understand need to get under the main PCB.? ? Thanks for any advice.
