Measuring approximately 15.5 inches long, 9 inches wide, and 6 inches tall, this heavy-duty tester features a sleek, silver-colored metal exterior with black rubberized feet for stability. The front panel is adorned with a series of knobs, switches, and gauges, each serving a specific function in the testing process.

The Weston F-2611-R1-755 Tube Tester has a total of 13 test points, which can accommodate various types of vacuum tubes, including triodes, tetrodes, and pentodes. Each test point is clearly labeled with a corresponding number and tube type, ensuring easy identification during the testing process.
