Introduction. This is a simple one-valve radio for AM reception from approximately 500kHz to 1.8MHz. It should be possible to build it over a weekend and it doesn't ...
Be that as it may, the "Beginner's One-Valve Set" included (with other popular BOP designs) in Gilbert Davey's first book, Fun with Radio, published in October 1957, is clearly descended from the 1948 design.
Building A One-Valve Radio Receiver This manuscript is 14 pages in length, has 4,244 words, and 30 images, mainly colour photographs. It contains full instructions for building the receiver, including how to make the aluminium chassis, and where to get the components and valve.
This is a one valve [tube] radio that believe it or not I constructed 48 years ago. It remained lost but was discovered again during a recent house move. The valve used is a battery R.F. pentode ...
Fig.1: the "G. Marconi" was a basic regenerative radio receiver employing a single 3V4 valve. Its output was coupled to low-impedance headphones via an audio step-down transformer. Its output was coupled to low-impedance headphones via an audio step-down transformer.

A Simple 3 Valve EF91 radio A long time ago in a shed far far away I built my first ever valve radio. I was 12 years old at the time and to my parents dismay I decided to move on from OC44 transistors to those high voltage warm things called valves.
In electronics, a vacuum tube, electron tube (in North America), thermionic valve, tube, or valve is a device controlling electric current through a vacuum in a sealed container.
The diode valve or tube is still widely used and in years gone by, vast quantities of these devices were used. The diode vale is the most basic of all thermionic or ...
The culmination of this interest in simple Single Channel radio is the conversion of period Single Channel sets to 2.4g using Phil's custom electronics described on the projects and workshop pages.
