One Tube Radio Schematics

There is a very nice schematic diagram of the radio with a parts list all on one page.

One tube radio schematics. Single vacuum tube radio with circuit diagam operates on a 12v to 25v htlt supply duration. There is also an explanation of how the radio works what the vacuum tube does and how to operate the radio. The radio is a regenerative receiver using a combination triode pentode tube which is like having two tubes in one so i guess this is actually a two tube radio. It was possible to run a vacuum tube on very low voltages by switching the two grids.

The triode section is used in an armstrong regenerative detector and the pentode section is used as an audio amplifier. For the nostalgic or the enthusiast who would like to build an updated version of this classic radio ive included schematics parts information assembly documentation and pictures of a completed and tested one tube am radio based on the original from 1968 which is itself derived from a design attributed to lee de forest in 1908. The response was very positive as most people look at the schematic first when they are looking for a project to build. This is my homemade one 49 hikers tube dx radio.
