FS: Knight-Kit 600A tube tester(88 YX 143). This is a nice working tube tester from the early 1960s. Good cosmetic condition. The control panel is near perfect. The case shows some wear, but not bad. The Roll Chart lists over 600 tubes and there is a supplement chart with even more tubes listed. The tester measures emission, shorts, open tube elements, and cathode to filament leakage. It accepts 4, 5, 6, and 7 in large tubes, regular and miniature, octal, loctal and 9 pin miniature tubes. This unit has been tested with several tubes and compared to my Hickok 6000 tester with similar results. Picture available. Price is $125 plus shipping. Thanks, Charlie Hugg, K5MBX
