This tube tester features a clever voltage control circuit that eliminates the need to constantly set the AC line level to insure accurate tests, regardless of line voltage variations. Has sockets for most late model hifi tubes, including compactrons, novar, duodecal, and Nuvistors. Dyna Jet System, where many popular tubes can be tested by just setting two dials. Dual section tubes can be checked with just two pushbuttons. Sensitive grid leakage and shorts read on the meter and on a neon lamp, indicating grid emissions, internal shorts, or gas. Life-test pushbutton, which will indicate on the meter, gives indication of relative good use left in a tube.

The tester works great. I checked it out with the following tubes: 6BQ5 6V6, 12AU7, 6DJ8 and 5U4GB which had all been tested on my Hickok 539C and TV-7/B. The readings were all satisfactory. Includes the instructions and the tube tester settings.

The meter does have a crack and some scuffs but they are strictly cosmetic. The case has some wear. The tube socket pins are tight and the 12AU7 dual triode socket which would probably have seen the most use is tight as far as the pins. With many older testers, the pins may loose from lot's of use and this may cause contact problems.

With the exception of a few scratches, this tube tester is in very good condition.
