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.

Viridian,
Unless they have radically changed the design, the Tube Research GT 400 still uses OD3 tubes.

I still have some spare OD3's around here from when I owned that amp.
More to discover
