Was given a B&K Dyna Quik 500 tester. Powers up, fuse good, tubes power up, internal lights ok. Seems to be operational, but no booklet or chart to let me test it against known tubes or compare to my other testers. Outer suitcase is good condition with some discoloration and a small tear or two. Lots of articles about calibration and refurb. Booklet available for 10 bucks on ebay.
Dial knobs tight, selector knob gone but not needed. $65 plus $30 shipping in the lower 48. Will pull tubes, wrap, and put them inside the tester.
