Card tube selector tube testers
« : February 23, 2020, 07:41:41 AM »
Just was given a B&K tube tester that uses cards instead of myriad knobs to select the tube under test, no knobs have to be set each time. Does anyone have experience with one of these. Seems like a good idea especially when a lot of tubes have to be tested. I'm not sure how the calibration on it is, and it may need to have that checked and adjusted. But I'm looking forward to using it, even more so when I get the tube TV we're looking for... there's lots of glow-bottles in those '60s color TVs! Will add a pic when I get back from Florida next weekend, no pics stored on the wife's iPadAir.  We're checking out the Everglades today!
