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. Regards, Stuart Irwin |

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 |

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. Regards, Stuart
