5FP7 project starting with the focusing coil.

[AdrianPH]

Hello Trevor;

I tried going through the old Practical wireless magazines on the Internet to see if there was any valve receivers for the old Baird system without success in finding any. The frequencies are much different from the old 405 TV's that I felt what I was reading in the TV articles did not match.

I need to go and work out a few more scan coils with thicker wire, less turns and more current to see if I could match a speaker transformer.
