Description

Ameritron products are typically housed in metal rack-style or desktop enclosures with large analog meters, heavy-duty transformers, and front-panel tuning controls. Most tube amplifiers use grounded-grid designs employing common transmitting tubes such as the 811A, 572B, or 3-500Z.

The product line has included both vacuum tube and solid-state amplifiers, along with matching antenna tuners and RF measurement equipment. Ameritron equipment has been widely used in amateur radio contest stations due to its relatively high output power and comparatively moderate cost.
