[Amps] Alpha 87A Won't Transmit

[Frank Kirschner]

My Alpha (actually, the whole station) was turned off but plugged in for
about nine months while house renovation went on. Finally was able to make
my way to the rig, and when I transmit, the Alpha immediately goes to
standby showing SF 14. With the amp in standby mode, I can transmit 100
watts from my Flex 6600 with low SWR. I checked all the connections and
cleaned the RF connections. I also ran the Tune and Load controls up and
down, and they move fine.

Any ideas?

Thanks.
