Sp Vacuum Tube Tester Nri Professional Model 67 #5
Description
A vintage NRI Model 67 Professional Tube Tester made by Triplett Co . of Ohio and based on the same specs as their model 3413. This very practical tool used in testing vintage amps and radio tubes, is used in determining what really needs replacing when restoring these sets. It tests all the old types of tubes from 01A’s thru 12AX7, as well as green eye tubes. It has 4, 5, 6, 7, Octal, Loctal, Miniature 7 and Miniature 9 pin sockets as well as pilot lamp testing socket. Measures the emission value as well as tests for shorts, open elements, filament and tap continuity which is roughly anything that can basically go wrong with these tubes. It works as a very good basic tester. It doesn’t test for gas.
