    Description

    This listing is for a
    Vintage Hickok 532 Mutual Conductance Vacuum Tube Tester.
    This is a decent tester but, due to its age it will not test a lot of tubes I have.
    Actually it can, I just get tired of having to look up settings on line as I cannot get a modern roll chart.
    This comes with a very good model 533 roll chart (installed) which has a lot more tubes on it than the original 532 chart had.
    Cosmetically looks its age but not terrible.
    Well, the top cover is pretty terrible but it is intact and serves its purpose of protecting the tester.
    This tester has had its rectifiers replaced with solid state devices.
    The 5Y3 is a simple plug in replacement and does not affect calibration.
    The 83 replacement is a special device, known as an SS83R, which is properly regulated to correctly replace the 83. I purchased it from an eBay seller.
    Instant on is pretty nice.
    Now for the issues:
    1) I do not get good agreement between sections of a known-good 6DJ8 tube. This should be an easy fix.
    2) The Aluminum position indicators for the selector switches have some lash, as do the indicators in most examples of this series of testers. It is still possible to properly locate the switches, I just needed to let you know about this.
    3) You will need to add some resistance in the Line voltage set pot because modern power lines are 120 volts, not 110 volts that was common when this was built.
    4) You should calibrate it once issue 1) is corrected.
    I did replace the paper capacitor and the electrolytic capacitor.
    I cleaned switches.
    You can keep the socket savers you see.
    This is guaranteed to be as described.
    Since this has no vacuum tubes, it can ship through the eBay Global Shipping Program.
    I am happy to answer your questions to the best of my ability.
