[QUOTE="digdog, post: 381737, member: 175295"] And many enthusiasts built their own using War Surplus bits such as radar tubes - there were magazines such as Practical Television which gave pretty full instructions -and loads of shops selling surplus valve and electrical bits and even full kits. Costs for the most modest TV were horrendous - and they took quite a few minutes to warm up and settle down to show a watchable picture. Technology was in its infancy and as others have said the techniques to generate sufficient eht and manufacture large screen tv tubes were not known back then. It was good fun to strap a huge magnifying glass on a 9" screen to try and kid everyone it was a 12" - and even more fun to sit at the side and see the distortions this arrangement displayed. Oh, and there was only one channel until about 1953 - happy days...... :) [/QUOTE]
