Default Re: Single valve receiver circuit required

Hi Les, a copy of the book Radio for Boys (Bradley), or A Beginners Guide to Radio (Camm) will yeild the details you need, together wth a simple explanation of how they work. If you are in the Newcastle area I can show you copies of both.
The Camm book goes as far as showing how to make your own coils while the Bradley book is a progressive set that will allow you to extend it to a 4 valve LS set. My son built this when he was 8. Commercial coils are required for this one, but should be available on e-bay.
