click to view full size image 539A   -   Hickok Tube Tester. This is the early version of the famous 539B/C Series Engineer's model, one of the finest testers ever produced. Like the 539B and C, this tester measures true transconductance. This tester differs substantially from the 539B & C and unfortunately the settings from the B&C don't work for the 539A. * Separate meter for monitoring and setting line voltage so that more accurate tests can be made. * Separate meter for monitoring and setting control grid bias voltage assures the most accurate test possible. This meter also doubles as a ammeter for testing V-R tubes * Main meter is calibrated in micromhos, the unit of transconductance. * Provisions for adding an outboard meter for monitoring of plate current. * Provisions for attaching a cathode resistor for self-biased tubes. * Neon light indicates shorts or leakage current between elements. * Tests 4pin, 5pin, 6pin, 7pin, octal, loctal, 7pin miniature, 9pin miniature, acorn and sub-miniature tubes. Good Roll Chart. Used Checked.
