Hi,
Just spent the day working on a friends BC-610. The rig appears to be
working but output is about 200W at 300ma but the 250th looks very yellow
and bright glow as if its not tuned and radiating too much heat. I checked the
bias
and found the required -110v but when the exciter is turned on the bias drops
to zero!
I'm assuming that when keyed the bias also goes to zero and thats why the final
looks
so hot and the output is low. If I take the rectifier from the exciter so that
there is no power
to the exciter then the bias stays at -110v when the exciter switch is turned
to the on position.
Why would the bias go off when the rig is keyed on? Any ideas would be welcomed!
Thanks and 73, Bob, AA8A
