Default Wikipedia Vacuum Tubes. HUGE amount of info!

https://en.wikipedia.org/wiki/List_of_vacuum_tubes

Found this when googling for 500mA low voltage barretter.
I got completely sidetracked for a while.
It is a huge compilation of information.

I have now also been very much side-tracked!
Thanks for the link, what an amazing compilation.

Yes David. Not your ordinary valve data base quick one stop look up. But an insight to the entire World methodology of valve identification and how it evolved.
Even points out the possible clashes and how they ere avoided.

Thanks, Rob! Some midnight oil has been burnt to compile all of this information. I just have to set a bookmark.

Though I did not find one of my favourites, that 6B4G audio valve.

Great to see all the valve numbering systems documented in one place, especially to point out to some parts of the world that not everyone uses the RETMA system!

Of course, now I'm trying to work out which system various valves with odd numbers fit in to, and I can't work it out for the 12E1 and S11E12 series pass valves. The 12E1 ought to fit in to the Ediswan/Mazda system but doesn't, and doesn't seem to suit the STC system either. The S11E12 is a complete enigma.

I'm not a valve man, but was interested to explore that list.

A touch switch, a digital memory, and an analogue equation solver, all made from bits of metal in a vacuum.

Very clever !

An interesting compilation, but as you mention has some inconsistencies so not up there with other sites (Valve Museum, RadioMuseum) for reference material. None of the CV tubes as far as I could see, at least not CV4024. So then I am thinking, what's the point?

For instance, recently there was a query on another site about the potential demand if a new Magnoval (B9D) base was to be manufactured and Radiomuseum had a search facility that returned a list of all tubes that had that base.
