does it matter Rich? to me the single 3-500Z amps today are junk.
(junque for the higher classes) my data tells me that at 3,000
volts, the max plate current should be 370-400 ma and get 750 watts
out of it....how can these amps be linear?????
Unfortunately, the ARRL lab doesn't seem to have tested the Ameritron
AL80B (or any of the AL80 series), but the specs call for -35 db or
better 3rd order IMD. This is the same spec as the Alpha 87. -35 db is
better than most transceivers: the ARRL lab measured -31 db from the
Yaesu FT1000-MP Mark V Field in its normal mode, and -40 db in its
special class-A low distortion mode.
I think the AL80 series is as clean as most modern amplifiers.
