In fact the fault in the video amplifier was a simple one. The 15Kohm anode load resistor was short circuited to the centre spigot of the valveholder. Repositioning the component effected a cure.
40 volts of active video + syncs is present across the load resistor of the video cathode follower.
Assuming the CRT is OK this set will display a well contested picture.
