• Model: Dynamic Mutual Conductance T. T. 750 - Hickok Electrical Instrument

• Shape
• Tablemodel, low profile (big size).

• Notes
• Hickok 750 is mutal conductance tube tester wich measure transconductance on vacuum tubes delivering less than 25 watts of power, transconductance is measured in 5 ranges up to 30000 microhms. It also has ability to test: leakage, gas, shorts, life, continuinity, noise and rectifiers. Another feathure of 750 is improved ballast and voltage regulator tube test. Two versions of 750 exist, early with neon lamp for shorts test and late with megaohmmeter function for shorts (circa 1957). Bouth versions have 11 sockets and similar apearance but some differences in rejection values are noticed. 750 has greatest repeatability of test results among all Hickok testers.
