Default What is the biggest 300B tube? (Dimension)


I got one project running and it will use 300B's. What is the biggest size of 300B that is out there?

There is a lot of types out there, but lenght are not always mentioned.
I do not want to limit tube selection due to a too small cage or space for it.

Like TJ300B mesh type is 15,5mm long plus the pins. Is this the longest one? http://www.emissionlabs.com/datashee...mesh-final.htm

Thanks for any help.

Some of the tubes made by Vaic and AVVT were quite large, there are still small stocks of these tubes NOS and they show up used from time to time as well. Jac music would have information on these.

The 300B tube history. What history?! It is alive!

Also Kron currently produces the 300B as well: Tubes

The TJ globes are quite physically large compared to the generic ST glass versions..
