Hickok 6000A Tube Tester

I picked up this tube tester as a trade for refurbishing an amplifier and a tuner. The history of this tube tester is that it was used by P & G (Proctor and Gamble) and then surplussed out some years ago. The case shows some wear, but the deck and electronics appear to be in excellent shape. The original power cord is still in excellent condition. I checked the calibration and it was spot on and didn’t require any adjustments. This is a very nice tube tester that doesn’t appear to have seen much use.

The 6000A is a compact unit that tests the newer tubes like Compactrons and does not test the older 4, 5, and 7 pin tubes. I use this tube tester as my everyday tester for newer style tubes.

I especially like the shorts indicators. With a quick glance you can see if there are any shorts before testing the tube for quality.

    If you can do a line adjust and test tubes, then the 83 and 5Y3 rectifiers in the tube tester should be good. It probably just needs a calibration. The Hickok tube testers are high quality instruments and need regular calibration to keep them accurate. My Hickok 750 tested every tube shorted until I did the calibration. I doubt your tester is bad if you can test tubes, albeit inaccurately.

    It has to be checked by a technician to know for sure.
