Looking for a good 300B datasheet

Does anyone know of a good 300B data sheet? I have been googling like a mad-man, and haven't found one thats good yet any help would be great.

Here's another site that might be useful. Note that the WE 300A is electrically identical to the slightly later 300B. I am not sure what the exact differences are between the two, but the 300A is very rare. I've seen just one pair.

You can find the datasheet for another current production tube at the JJ website - JJ300B, note the difference in filament current rating.

Look here. The 2nd of the 3 sheets has USEFUL operating condition data.

I am not sure what the exact differences are between the two, but the 300A is very rare.

The difference is in the the location of the bayonet pin. The 300A is the same as an 811A, 830B, etc. The 300B has the pin in its own special place.

Hi John,
Thanks for the info.. I knew it was some trivial detail, but just what it was I didn't know. Any idea why they decided to change the bayonet pin location?
