Good tips...all of these. By the way, this is the worst schematic I have
ever seen on any piece of electronic equipment.
I take it that the 80A was built by another company which was bought by MFJ.
I'm beginning to think we should convert this amp to an 80A even if the
active bias ckt is not the culprit here.

Thanks,

As I understand, Ameritron first came out with the AL-80 which wasnt too
good, then Prime Instruments bought out Ameritron and upgraded and
improved the AL-80 into the AL-80A. After that it gets cloudy. I think
MFJ bought the ham stuff from Prime and came out with the AL-80B. Even
though my AL-80A says Ameritron on the front the back says Prime
Instruments.

If anyone knows better please come forth.

The AL-80A is a good amp for the money, $500-$800 . Power out 800 to
1000. I don't like to push mine too much so I keep it down around 800
in SSB. Also I usually don't use a amp, 100-200 watts gets the job done
most of the time.
