Re: The BBC 1 Valver!
I can remember the construction of a one valve radio being described on the BBC in the 1950s. I thought it was on Blue Peter though, in the days of Christopher Trace. One episode suggesting connecting a torch bulb across the heater pins of the valveholder. If it blew you had HT on the pins and needed to correct it before inserting the valve.
I would like to have built one, but in those days I couldn't afford the cost of postage for the plans, yet alone a kit of parts.
