  • Does Hickok still repair vintage test equipment?

    Hickok Waekon operates a service center for their modern automotive and diagnostic tools. However, for vintage vacuum tube testers, you will likely need to consult specialized third-party repair services or follow the schematics provided in the equipment's original manual.

    Roll chart settings and specifications are often included in the original user manual or provided as supplemental tube data sheets. You can browse our collection of Hickok documentation to find the correct dial settings (filament, plate, grid, etc.) for various tube types.

  • How do I check for tube shorts using a Hickok tester?

    Always evaluate a vacuum tube for shorts prior to performing a mutual conductance test. Set the tester to the SHORTS position and observe the neon indicator lamp while tapping the tube gently. If the lamp glows steadily, the tube is shorted and should be discarded.
