5 pin tube tester

Herman,

I don't know what to tell you but I am now looking at the OD3W tube. I only see - 6 pins -

thanks for the other info.

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.

Viridian,

The tube in questions was a " OD3W " Although I did notice a few OD3 in the pile as well. But these tubes are not the same. For what it's worth the OD3 is also employed in the new BottleHead pre III.

Herman,

Some tubes have marks but most of what is in question has nothing. These look to be of the pre amp type.

I have many large tubes thought that I can read the numbers but am not able to test on my tester. But for now I will wait until I decide if I'm going to pursue the tube quest further. I orginally bought this mess of tubes becuase of a couple that I wanted. They came very cheap. Some of these are really cool looking. To bad I can't find a use for them.

Some body sent me a e-mail expressing an interest in some of these tubes. However I misplaced the e-mail. If you want you can write me again and I will send you a list of variuos tubes.
