Hi Ed,
Now you should know that to be indoctrinated into the world of prewar tellies you have to be able to complete the following verse:-
"A mighty maze of mystic magic rays..."
This video of my set should help you answer that one and hopefully give you some encouragement. I know that these restorations can get a bit daunting once the scale of the work sets in. I was halfway through the restoration of my set when I learnt that we had a baby on the way! I'm sure you will get there in the end. The fact that you have already had first light from the tube that proves it is a good one means that you have a good basis for a lovely set.
Enjoy:-
