So then I re-attached all the wires, powered it up and there was no video and the sound was always at full volume. Someone from ARF ('analog.tv') helped me figure out that there was no horizontal oscillation, which I tracked down to a bad couplate. I replaced it with the old one and everything was good - apart from the sound. I left everything out on the bench until I got a replacement couplate from Crist. I didn't really fix the sound until I was putting everything back together - I had re-attached one of the 50 wires to the wrong point! I also detached a power lead from the clock switch while I was putting it all back together. So I had to take it all out again to re-attach that lead to the clock properly. BTW here is a video.

Hi! Always nice to see a new member!
Predictas are adorable, congrats on successful restoration! What is a couplate? A hybrid network on a small separate board?

PCB based sets tended to be heavier users of couplates.
