Hi, Wayne. Have you tried manualman.com? Also, if you don't have his site, check out Chuck Schwark's home page. Just type chuck schwark in your browser's search window. I've heard of another place or two to get manuals, Vintage Electronics might be one. Try those places. You might even try the Nation Radio Institute (NRI), I think they are still around. Maybe they have the manual in archives. Bart
: I am looking for an operator's manual for a NRI model 70 tube tester. If anyone has one or knows where to get one, I would appreciate some help.
