Default Re: Baird T5 restoration project.

Well now I know the reason why the brightness control doesn't work in the T23. The CRT has leakage between the anode and grid, possibly a piece of cathode material has got lodged between the electrodes.
When the brightness control plug is pulled out sparks are seen to jump across the grid and earth connections of the socket.
