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.
