I remember visiting the UK's Vintage Radio Wireless Museum in Dulwich, South London as though it were yesterday. It's just an ordinary terraced house from the outside, but inside its a celebration of the tube (Valve) radio, especially in the era 1920-1950. What's more, Gerald Wells, who passed away in December 2014, was one of the world's experts on valves - and had a flood of stories about the famous names I heard second-hand as a child. Did you know that Vidor Batteries were named after the manufacturers two daughters? And what were the better brands of radios. Enthusiasts in the UK have since made a DVD about Gerald which I can recommend. Part Two of this programme I made in Dulwich one year later has also been released further. BBC World Service commissioned and broadcast an excellent portrait of Gerald on August 20th 2010. I am sure you could have visited Gerald 1000 times and still take away new and different stories about this era of broadcasting. Anyone restoring early iPods?
