Hi, I have a Knight Tube Tester that does not have a model but looks like a 600 series. Many of the tubes that I need to test are not listed on the roll chart or in the supplemental chart PDFs that I have found on the web. Does anyone know the proper tube setup for a 7591 tube? Is there a source for tube charts that cover some of the "newer" tube types?
Thanks.
Thanks.
