This is a very common B&W set and there are probably a number of parts chassis around. Else you will need to find a CTC5 parts chassis and a CTC5 convergence yoke to obtain both the socket and the plug to make up the needed cable.

Thanks Bob.

In the meantime until I find the appropriate connectore I shall extend the CRT and yoke leads and just leave the convergence coils attached to the chassis and off the CRT until I have confirmed a sensible picture.
