Yesterday morning when I turned on my TL-922A, there was a very loud pop
followed by blown fuses. I replaced the fuses, changed the setting to CW to
reduce the B+ voltage and tried again. Similar result with several smaller
pops and then blown fuses. I use a footswitch for T/R control and it wasn't
depressed nor was I transmitting with the exciter when I powered up. I
should also mention that I've heard a pop on power up two times previously,
but neither time caused a blown fuse. I opened it up today for a visual
inspection and see no signs of arcing or anything unusual.
Before I dig into this thing, has anyone else experienced this problem? Any
hints or suggestions to reduce the troubleshooting time will be appreciated.
Thanks and 73,
Clay W7CE
