Cassidy Nolen #1 Posted December 30, 2005 Well if you need this then you are a better man than me. I have had this for several years and never done a thing with it. Superior Instruments model number 85 Dynamic Tube Tester. Its for testing vacuum tubes. It has the book with a print date of 6/60. I was going to use it on the tubes in my Computer Space until I read the date on the manual.....they had not invented the tubes I needed to test! Anyway, worked on the ones I did test. Its in a little suitcase type thing for field testing. Overall in very good to excellent shape for being 45 years old and being a tool. Huh, tool. I'd like to get 20 bucks for fit. Shipping domestic priority would be 7. Let me know if you need a pic. Did not think it was worth popping one up. Don't know if anyone here fools with "this old" of stuff.
