Description

Up for sale here is this used vintage US-made 5U4GB rectifier tube. I tested it on my calibrated B&K 747B tube tester, and it tested at 70/70 or higher, on a 0-120 scale where 65 is minimum good, and did not have any shorts or grid emissions. I have a bunch of these available, and they're all from the 1960s and 1970s (a few may be 1950s) and are all US-made. They are from a wide variety of manufacturers--RCA, GE, Sylvania, Raytheon, Westinghouse, and possibly others. The tube in the picture is just for reference and is not the exact one you will receive. Please see my pictures for details. US shipping and handling is $5, and international is $18. If you have any questions, please ask. I have more tubes and other vintage electronics listed--feel free to take a look!
