Hickok 539A Tube Tester for parts or repair, the tester powers on and I tried testing a couple tubes but the test meter does not register any movement, the Line and Bias meters appear to function just fine but the MICROMHOS meter needle does not move, it is not known if the meter is bad or if there is another issue.
This a hard to find size, it is used for 4 in by 4in square steel tubing with a gauge wall thickness of 7ga to 11ga however I have used these for 14ga and it worked fine.. get these will you can at this price look around if you need to but these are priced to move.. $4.95 for each plug Product Features The tapered rib design works efficiently on the inside of the tube to ensure a tight fit.
This device has a CUSTOM ENGRAVING on the chrome Chestpiece finish including a logo of a alligator head and the phrase "In memory of Ludwig Salamon." SEE PICTURES FO
Dual headed Stainless Steel Stethoscope, with light Green Tubing. The Stethoscope has never been used. I received the Stethoscope as a joke birthday gift.
