Looking for help testing a Western Electric 306A

[nickdinatale]

I recently picked up a box of assorted tubes at a flea market and had a pretty exciting find in it - a US Navy branded Western Electric 306A that looks pretty promising. With the value of the tube, I'm not willing to take a chance at testing it with the wrong settings, so I'm coming here for help. I have an Eico 666 tester, so the available charts are certainly not old enough to have included any settings for Western Electric tubes. I've included a link to both the datasheet for a WE 306A and the manual for the Eico 666 for anyone that may be willing to help out.

P.S. If anyone is able to help out and I end up selling the tube, I will gladly make a donation with some of the money from it to AK in your name(s).

Bumping this for the weekend crowd - any help would be much appreciated!

Why not contact Western Electric? Im just about to post about a recent visit to the Western Electric plant in Rossville, GA where I found everyone to be friendly and eager to share information. They may not be able to help but then again they might. Phone 1-404-352-2000 and email support@westernelectric.com.

Hi:
RE: WECO 306B Tube
The RETMA base diagram designation is " T-5CB " from the 1955 Radio Amateurs Handbook from the ARRL , American Radio Relay League.
I can find no other tube with the same base connections.
Hope this helps
Ed

Best would be to find someone with a WE branded Hickok tester. I Have one but the 306A is not on the roll chart nor in the extra WE tube data that came with it.

It is a pretty close cousin to the 336A (as well as 6V6). You could likely work out a test routine from those tube datasheets.
