don't want to bash Ameritron but I have a friend who bought an AL-1200 and
did have considerable problems with the electrolytic capacitor bank on the HV
power supply. They did not have a good safety margin on their ratings when
compared to the output voltage. My friend recommended a good US source for
an electrolytic that would allow a safety margin. I seem to remember he blew
out the caps a couple of times before he got rid of it. A great looking amp
with a problem that needed to be fixed and Amertron unwilling to fix it
properly. I own an ALS-600 solid state linear and have experienced problems
with
the open frame relay. I read on Eham.net that others have also had this
problem. I am currently looking into replacing it with a Gigavac device but
once
again, think Ameritron should either offer a QSK vacuum relay as an option,
standard, or some other type of fix. I have had two Ameritron linears, the
AL-80A was OK (also blew a HV electrolytic but plenty of space to
fix it easy). Overall, my opinion is Ameritron is good but they need to
listen to their customers a little better and fix problems a little quicker.

Probably using the GREEN lead on the transformer which offers HV at 4KV. It
is only for those who have low line voltage. I'll bet that was the problem.
