REPLY:
Yes on CW, but don't run full power on RTTY. Mine smoked the tank coil
twice, once on 80 and once on 160. I asked the designer, W8JI, about it and
his reply was "Who runs RTTY on 160 meters?" Well, me for one. :-)
It was the polystyrene support rods on the coils that melted. As I recall,
the higher bands don't use that kind of coil and there was no problem there.
If you really want the AL-82 you might consider cutting a hole in the side
and mounting a fan to cool the tank coils. That would void the warranty of
course.
Also, of all the amps I ever owned, the only one that ever blew a tube was
my AL-82. Fortunately, Ameritron replaced it under warranty. That is a very
expensive tube if you have to replace it yourself. If I were going to buy an
Ameritron I'd get the one with two 3-500z's. Much cheaper to replace.
