The Interesting thing about the rectifiers for the time bases is the 6 diodes in series. They have a forward breakdown voltage of 0.165v and a reverse voltage of 2.9v they actually work although one was short circuit. I've now replaced them with 6x 1N4007 instead. The HT for the time bases is around 2v lower now.
180 volts AC to the set gives full width so next is to rig up something for the RF stages to at least give me video.
I believe Frank's programmable standards converter would accommodate the necessary requirements of the set.
