My Dad made our first TV set, out of old airborne radar sets...these used Philips EF50 valves, and that's a story in itself....
The EF50, the tube that helped to win the War
The first programme we saw was the last King's funeral, the picture appearing by magic on a smeary 9" screen. It took several years, and two attempts at cabinet making, before the various chassis were finally contained in a cabinet. Dad's attempt at rivetting the chassis was rapidly replaced by my Aunt Lil, who did a very rapid and professional job of flush rivetting, having spent the War making gun turrets for Lancasters!
