Hickok 533A Tube Tester Calibration

 

   

 

This customer was unfortunate enough to have purchased a tube tester from Ebay which was dead on arrival.   The Hickok 533A is an excellent tube tester, IF it worked properly.   

 

We completely recalibrated the tester, and replaced numerous defected parts.

Some of the parts were no longer available and had to be replaced with modern substitutes. 

  

The tube tester now measures tubes correctly.

 

 

Total Cost of Repair: $ 250 dollars including $ 50 dollar in parts

Turnaround Time: 1 week
