In Reply to: Hickok 539A tube tester -- Fix or ditch? posted by Rod M on August 14, 2015 at 11:00:52:
You must try to fix it. Take the time to research. Lots of online resources exist. The old Noel Lee info was mysteriously withdrawn, but some slick folks recycled some of the info. Military repair manuals, like the TV-7 TM-11 is a good start.
Chances are that the link to that TM-11 reprint will also have some added "hints and tricks" courtesy of the good repair folks out there. I have seen a reprinted manual for a 600A series which had some good tricks and cool calibration info included. Certainly, a $15-$20 reprinted 539A manual/test data/cal & tricks info included buy on epay will make the resell worth that much more. But, before you spend some money, go googlin...
The trick to free a stuck meter with bits of masking tape held carefully, removing the offending stuck dirt or metal sliver can be seen in print for free. Likewise, that electro across the meter might do the trick. DO NOT wire a battery across any meter without a resistor bleeder installed to test the meter. Meters are easily damaged; but you know yours will work since Line Adjust is OK. Research, plan the attack, conquer the technical obstructions and stardom with richer pockets awaits your smiles...
