Default Re: Single valve receiver circuit required

Google 'One Tube Radio' (we tend to forget the Americans) lots out there.

Every now and again I knock one up just to see how good one valve is. Any battery valve wired as a triode (if needed) as per attached sketch will let you listen to the world. Anything approximatly like it will (probably) work.
