Tube Type A
Hello Giuseppe,
This tube reminds me of the type made and repaired (yes repaired!) by G. W. I. Valves of London, W. 1, about 1925/26 time. The glass type, paper label and print are very similar. Have a look at the tubes in the Unknown Section at H. M. S. Collingwood, the Royal Navy Radio Museum.

Thinking a little more about this, I wonder if the Type A was just a general purpose meaning for reconditioned tubes with a 4 volt filament by G. W. I. or even another manufacturer?

A Valves
Dear Guiseppe and John,
There are now 8 valves designated "A" in the museum.
BTH CeCo Messerkontact Moorhead Nelson Philips Radio and Telefunken.
Because of present limitations in the search engine these can only be found easily by searching on A_ rather than just A this will show them all.
A large number of companies produced the A - presumably their first one. Sometimes their last too! However none that I know made the "Jedebe".
I have a box lid of the same Jedebe valve with identical data to Guiseppe's.
I can find no reference to Jedebe but have seen several of their valves in the past all with the colourful label. I suspect that the name is a brand - possibly made in France but would much appreciate any information that would assist.
Kind regards,
Roy

Hello Giuseppe,
There is now a type A_Jedebe valve created and it would be very useful if you could upload your photographs to the page.
Many thanks for bringing this into the museum.
Best regards,
Roy
