Pictures of my KW Linear Amplifier

I recently purchased an Ameritron AL-80B 1 kW amplifier. After searching the internet, I realized there are very few good pictures of the “workings” of these amplifiers. Since many hams, like myself, love to see what’s “inside the box”, I decided to take a few pictures, and post them for others to enjoy. This is my spare amplifier, which I store at my Son-in-Law's (W6WWC) in Holister, California. It's a grea deal for him, and If I ever need it, I know where it's at :-)

The AL-80B uses a single 3-500ZG tube, and provides 800W on CW and 1kW Peak on SSB. It’s a sweetheart, very quiet, and weighing in at about 48 lbs.

The full manual is available at

Hope you enjoy the pictures.
