With the handle "KT88", I would think that you would want an octal tester.
5 pin tube tester
Does anyone know a brand of tube tester that would test a 5 pin tube? I would prefer to get by as cheap as possible. I bought a bunch of tubes and have come across some that my tester was not designed for. One tube I'm particulaly interested in testing is a 2E22. I also have 6 pin tubes that do not appear in my tube measurement guide. Such as a OD3W. Very interesting tube! I would be curious to know what it was ( can be ) used for.

http://tubedata.tigahost.com/tubedata/sheets/127/0/0D3W.pdf Is this the tube? If so that is where the confusion lies. It is considered an octal (8 pin) tube because it fits in an 8 pin socket. It does have only 6 pins though and only 2 of those are actually used. |
Yep that's my tube, except mine is a Raytheon. Looks to be band new but no way to test it. I also found some on ebay over in the UK. Sure whish I could find someone that needed one. I was also hoping that someone that had a tube tester could look in their manual and tell me if they can test such a thing. Then I would know what tube tester could be purchased. I also have some big 4 pin tubes with no name on them I'm wondering if there is a web site that expalins how to id tubes. |
KT-88 my Hickock 752 will test the OD3, but really it is of little interest as it is not used in any audio gear. Very hard to id tubes, but usually they had paint on them at one time and it simply wore off. Breathe onto the tube, often your breath will show the hidden markings. I have used this tecnique and it has really been, ahem, revealing. Oh, and having Jack Daniels on your breath does not help; it just makes it more fun. |
