Western Electric Tube Numbering

[KA8WTK]

All,
  Does anyone know of a cross refference for Western Electric tube numbers to "normal" tube numbers?

Thanks!

For most of the WECo tubes, there was no mapping to off-the-shelf "normal" tube numbers.

However, some WECo tubes like the WECo 396A, also appeared as a 2C51 and 5670 and were made by other manufacturers. The WECo 393A also appeared as the 3C23 and 7410. The WECo 417A also appeared as the 5842 and the CV3789. The WECo 403B also appeared as the 5591. There may be others but that's all my brain is spitting out at the moment.

A few more:

350A=807
350B=6L6G
349=6F6
274A=5Z3
274B=5U4G



Lud Sibley's book "Western Electric Tube Data" (not Tube Lore) is invaluable, naming everything they made, cross references, and engineering/production data.

I believe it is out of print now, Unfortunately.  It was available thru Antique Electronics Supply.

If you need some particular data fast, PM me and I can look things up for you.

Those old Western Electric tubes are no good. Pack 'em up and send them to me, I will safely dispose of them. No charge.

Do not deliver.

Really,....
You guys better watch out what you say on this board. 
Some readers might thinkg WE's are worth taking to the next tube shoot.

..cause,

Professional driver. Closed course. Do not attempt.

You're right Rick, we need to insert the disclaimers.

Like the time I posted how I reputedly had a big jug of R-12 and was using it to snuff the flames out on the Weber grill when the steak fat fell on the charcoal.   "Works great!"

Got a lecture about phosgene gas.

We used a lot of the Western Electric 407 and 408 tubes in our multiplex equipment in the late 60's. They were a 24 volt filament version of what I though might have been the 12au7 or 12ax7 but not certain of that.

The 408's were pentodes.
The 407's were dual triodes but pin configuration was not the same as the 12AU7 or 12AX7. The 407's were also 40/20 volt filaments.

40 volt fils? ? ? ? ?  Now, that is strange! But, WE tubes have always been their own unique animal!

Ir drops from Maybe long runs to amps under the sea. .?

Everyone wants to help me clean out the shack! 

Seriously, I'll put a list together and we'll see what I got.
