This is a Hickok 600A tester that has been repaired and calibrated. I sourced and installed a new meter, replaced the power cord and new shorts lamp. I also added new an 8 pin and 9 pin socket savers.
The case shows a lot of wear, but the tube tester is electrically in excellent condition. Older style meters used in vintage tube testers were not as robust as new meters. Now with the new meter, the tube tester can be expected to work very well for a long time.
The Hickok 600A tester is $350 plus shipping to the lower 48 states only because of the weight.
Contact Me if you have a tube tester you want calibrated.
