Smile Re: The B4 valve base. Now 100 years old?

Hi,
Bush were rather partial to the B4 plug & socket. I had a TV43 which had two. One from the RF chassis to the main chassis. And another for the scan coils.
Cheers, Pete.

Default Re: The B4 valve base. Now 100 years old?

Isn't the AD3, B103, B130, B136 and B137 Battery packs (1.5V & 90V) using the B4 base, with of course the LT on the pins normally for filament, +HT on what was often Anode and HT- opposite?
I think they last made about 1968?
