The Hickok 752 is an excellent tester that was aimed at the two-way radio business. The 752/752A has some special features not found on most Hickok tube tester. One of these features is the ability to check double section tubes (like 12AX7) without resetting the selector switches to test the second triode. You simply push the "Plate 2" button and the quality of the second tube section is automatically registered on the meter. This makes this tester an ideal one for the audiophile market as audio equipment is typically loaded with double triodes.
Checks mutual transconductance for tube quality test which is the most reliable test known.
Meter has only one scale which makes it easier to read than most other Hickok testers. A mutliplier switch is set rather than using several meter scales.
Handy "Plate 2" button allows for testing double section tubes without resetting selector switches.
Meter and roll chart are backlit....another feature not found on most Hickok checkers. This feature really makes the tester a joy to use in darker rooms.
#49 light bulb acts as a bias fuse to protect the sensitive bias poteniometer.
2 plate voltages available.
Life Test button
Terminals for attaching external self bias resistor.
Shorts and leakage are indicated on the meter rather than a less reliable neon bulb.
Sensitive gas test
