Col

I do have a good circuit diagram and things for the T311 in Volume VI of Newnes here.

PM or eMail me if you want to pop over and borrow it.

The valve is a U191, efficiency diode. As for the U25 connections, the anode is the one by itself and connect to the overwind, the other two are for the heater with one side connected to the cathode. One end of this goes to the final anode lead to the CRT.

Even though the overwind is not OC, any burning may be suspect and fail with high voltage on it.
