The Ameritron AL82 seems to me to be the most rugged and powerful amplifier
in the twin 3-500Z class.
The power supply alone makes all the others seem puny and the output is
higher than all others in this class.
They can be had for as little as $1200 used and are truly a contesters dream
amplifier.
