Now available a digital meter set for the 539B & C versions only

It's quite easy to convert and come with easy to follow instructions. The meters fits into the original cut-outs and mounting holes for those testers using the original Bakelite meter. If your instrument has the later all plastic rectangular meter, it requires a bit more work as the cut-out hole will require enlargement.

The meters come pre-calibrated, with full installation instructions. Your tube tester must be in proper calibration and working properly for complete accuracy.

The main meter digital readout displays a percentage (0 - 100%) of the value determined by the function switch. Very simple to convert to micromhos. For example; a 50% read on range "D" = 3000 Micromhos.

For questions, don't hesitate to contact me.

If you are unsure of your Hickok's (model 539B or C version only) tester's working status, I can arrange to have it serviced & calibrated along with the meter installation, contact me for more info.

   Sorry but I m no longer offering the above meters replacements.
