Hello.
I have noticed that with this valve the pin connection diagram shown is incorrect. Pin 2 is the screen grid and the top cap is the anode.

Hi Stuart,
is this the correct pin assignment of the PM12A_UX?
Does the tube have a bajonet guide pin as shown in the picture?
Is the filament center tap connected to the suppressor grid, as shown in the picture?
If yes, I will replace the presently shown pin assignment picture by this one.
Best regards, Harald

Hi all,
Wolfgang's pin assignment picture has now been activated on the PM12A_UX page.

Hello Harald.
In answer to your questions: That diagram is correct except that there is no suppressor grid. The valve, from an example I have, does have a bayonette pin.
