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 minor 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 $95 plus shipping. Thanks,
Charlie Hugg, K5MBX
