A31-410w crt Pin 5 

In this crt ( like in the A31-120w type ) the pin # 5 is internally connected to pin # 1;

In questo tubo catodico ( come nel tipo A31-120w ) il pin 5 è connesso internamente al pin 1.

The filament (heater) current is 130mA @ 11v.

La corrente assorbita dal filamento a 11v è di 130mA.

A31-410w crt Pin 5 

The A28-14W is allegedly the same base according to a page scanned from a short-form catalogue (source unknown) and it does connect pin 5 and 1. My Mullard data for 1968 A28-14W also has pin 5 and 1 connected.
