F1 is the HT fuse which you need to pull. If you're not sure which is which, do the resistance test across the mains again. When you pull F2 the resistance will go high, when you pull F1 it won't.

Give it 5 minutes around 150V, then wind it up to full mains. All valves except the EHT rect will light up and the dropper will get nice and hot. Don't worry about a small amount of smoke and a horrible smell. It will pass.

Then you can plug the set in directly and use the variac on HT only as I suggested. Do make sure your variac is wired corectly with common neutral. It should always be done this way but it really matters this time.

Do you have a 405 line source yet? If not, see if one of the kind TV guys in the Newcastle/Durham area will lend you an Aurora. Makes life much easier and it's nice to hear sound and see a picture.
