Tube Finder Tool: Matching Vacuum Tubes With Transmitters

Finding a vacuum tube for your application can be difficult. That's why we've created a Tube Finder to speed up the research and specification process. Our Tube Finder allows you to specify your requirements and let us sort out the tubes for you.

Our spreadsheet covers a wide range of manufacturers and tube types, including Klystrons, Magnetrons, and TWTs. Use the nested sort feature to search by any number of specifications, including power, frequency, duty, and more. Then, use our Field Strength Calculator to determine the tube power you need. Once you find the right tube, H6 Systems will provide a modulator/transmitter to drive it.

The Tube Finder spreadsheet covers powers from kilowatts to megawatts, duties from .001 to CW (continuous wave), and manufacturers including CPI, Stellant, Japan Radio, and E2V. Columns in the spreadsheet include power, frequency, pulse voltage, pulse current, filament voltage, filament current, cooling requirements, tube type, manufacturer, pulse width, and duty.
