Default Re: 300 Ohm ribbon feeder.

I'm pretty sure all UK postwar TVs used Belling-Lee connectors and 75 ohm unbalanced downleads, but pretty much all valve era FM radios used balanced downleads of some description. The 300 ohm standard wasn't always used though - I've seen 180 and 200 ohms specified, and there were probably others.
