Summary edit
Title |
Photograph of an early triode valve. This is one of many clones of the French TM triode, introduced in late 1915 and manufactured in the UK, US, Netherlands, USSR etc. under various names. It is not an Audion (rather, it's the Audion killer that supplanted all earlier designs). |
