LINEAR AMPLIFIER
INSTRUCTION MANUAL
The Ameritron AL-82 is a 1500 watt output linear amplifier that
operates from 160 through 15 meters. The Ameritron AL-82X is the
export model and covers 160 through 10 meters. The AL-82J is the
export model for Japan and covers 160 through 10 meters. The AL-
82/X/J uses two 3-500Z tubes in a class AB2 grounded grid circuit.
CW, FM and RTTY efficiency is improved by shifting the bias deeper
into class B. The heavy duty power supply and RF components,
combined with a forced air system utilizing chimneys, provide long
service life for expensive components. The AL-82/X is shipped
factory wired for 240 volt, 50/60 Hz power mains. The AL-82J is
shipped factory wired for 200 volt, 50 Hz power mains.
