It all started when I was sorting the garage out (being shielded I got bored enough to take it on!) and amongst the "stuff" were some metal pattress boxes. Too good to throw out I thought!
A quick check showed that a B7G valve base fits the knockout holes, game on.
A look through "Radio" by Edwin Bradley took me back in time and a plan evolved.
The result a one valve regen (page 38 of the 1965 edition) from all salvaged parts and a few hours of enjoyable time.
I'd forgotten how sensitive these little circuits can be,it happily copes with dragging Radio5 out without being swamped by Caroline (I'm about 10 miles as the waves go from the Caroline transmitter)
I may move on to 2 valves, the SW receiver in May'65 PE which I first built back then.
