Hickok Model 539B Tube Tester For Sale

Selling an original Model 539B Hickok Tube tester. I researched online and this seems to be the most popular and versatile model. It’s missing one knob shown in photo and turns on. There is also some screws missing from the faceplate going into the wooden cabin. Don’t know much about this device but everything seems to be in good condition. Since I can’t test it and I assume it will need to be calibrated and serviced from what online says I will start the sale at 1 dollar. Please be aware that this is a relatively heavy item so shipping can be expensive to some places.

offer with confidence and check my response. Thanks and good luck!
