At least they have socket voltage diagrams that'll come in handy when troubleshooting.

I just picked up a 10T4 this past week myself, which has the same chassis as your 10T1. It's going to be a long while before I can get to work on it, so I'll be curious to watch your progress.

Do you have nicknames for American TV's in the UK? I know you call American cars over there Yank Tanks. Just wondering if you have other names for other stuff.
