Oops! I was trying to reply to the person looking for tube testers. I have available several Hickok Tube testers. Models 600, 6000, 533, 570, 539, 122 and 118. All have been gone through and have been cleaned, checked and re-calibrated. All are in perfect working order. We also do repair on Hickok and other brands of tube checkers and other test equipment. Email me for details.
Thanks JB
