Subject: [Amps] Alpha 89 strange behavior
Hi from Italy!
I own an Alpha 89 amplifier and use it for my second radio (IC765) in my
SO2R set up.
Till now everything was ok. But this week the amplifier sometimes jumps in
"fault" position even without transmitting and even without connection to
the radio. More than this, as I can transmit when I stop to PTT with
microphone or RTTY software, the 89 immediatly goes in "wait" position and
restart as just turned on (after a couple of minutes it's ready again and
red light "wait" turn off), but if I retry to tx again when I stop to
transmit it turns on red light "wait" etc. etc.
Tubes are ok because when PTT is applied with 50-60 watts amplifier gives
about 1,5Kw.
Any suggestion?
It's hard to find Eto-Alpha labs here in southern Europe!
