Thanks for the encouragement guys. I have now installed my novelty 0.5mfd cap, the next task is to replace the mains electrolytic with 100 and 470 mfd caps which is bulged and appears to have burst a small hole. I think this failure or the valve gone to air consigned the set to retirement and hopefully prevented many more hours on the tube. I have a working Sony 9-90UB (dual standard) running in 405 mode and produced some crude patterns and sound with a AF signal generator. At least this will give me some insight on the health of the set.

Hi Graham, your PC video + VHF modulator system is the route I may take. i wonder if a raspberry Pi could emulate something in place of the PC...
