Need help..... Have Alpha 87a that goes to Fault 9 like this Amp has been off
for month. Put switches in HIGH VOLTAGE (SSB), OPERATE, and turn ON. No RF
present anywhere, and of course, no drive...all other radios are OFF. Amp. sits
for one hour and 47 minutes showing READY. Amp automatically switches to Fault
9 and will not re-set via OPERATE/STAND BY switch. Amp has a history of earlier
automatically going to Fault 9. All PIN diodes have been changed 6 mos ago.
Ideas? 73,
