Hickok 600a tube tester manual

 · Hickok and A testers have no electrolytic capacitors. They use rectified but not filtered DC in a balanced bridge configuration to measure AC transconductance. See if it still draws current with the rectifier tubes pulled. Hickok A Tube Tester Operating Manual and Schematic Downloadable operating instructions and schematic. 10 pages plus schematic. Manual and schematic are separate PDF files. Free Downloads of Hickok Manuals and Data: FREE DOWNLOAD: Hickok A Tube Tester Files (Adobe PDF files). HICKOK A VACUUM TUBE TESTER- MEASURES Gm This tube tester is superior to the simpler emission testers for sale. It applies individual voltages to all elements and sends a varying ac signal to the grid of the tube under test. Its actual amplification factor is measured as a Gm value on the meter. Its the only way to truly match tubes in amplifiers.

This series is a Mutual Conductance tester equipped with a removable (without disassembly), interchangeable socket island. With both socket islands, the series will test all tubes designed from the early 's on. This version has the island for testing; octal, loctal, 7, 9 10 pin miniature, novar, duodecar (compactron), nuvistor. under specified conditions, the tube will test GOOD. The versatility of the Hickok Dy-namic Mutual Conductance Tube Tester makes possible a special test that will reveal a tube’s ability to perform under adverse conditions as mentioned above. This is possible because the tester measures mutual conductance instead of emission. THE TEST a. This test data is for Hickok A, A and A testers only. Similar model numbers (, , etc) are different, and this data is not valid for those testers.
