Valve and tube Frequently Asked Questions
http://www.thermionic.org/valvefaq.html
Valve and tube Frequently Asked Questions. To provide a little context for the site and explode some common myths I have drawn up a short list a "Frequently Asked Questions". If you have other questions you feel should be answered here, please email me at: andrew@thermionic.org. And I'll see if I can add these the list. Isn't this site taking valves a bit too seriously? Thanks to my friend Adam for pointing this out :). Aren't valves (totally) irrelevant today? In some specific applications no. There are...
Valve types
http://www.thermionic.org/types.html
Under construction. At present only voltage regulator tubes are mentioned. More details will arrive here soon . Voltage Regulator (or VR) valves are ingenious devices designed to maintain a constant voltage across their terminals over a range of currents. Such valves have a cold cathode and contain gases at low pressure rather than the conventional high vacuum normally used in amplifying valves. The internal gasses are deliberately chosen to ionise (conduct) at a particular predefined voltage. Gas discha...
Sansui 1000A
http://www.thermionic.org/sansui1k.html
Sansui 1000A hifi receiver. The first time I saw the Sansui I did a double take. I was surprised to see what appeared to be a piece of 1970's transistor hifi being sold at the NVCF, but as I looked away from the front panel and over the chassis I saw that this receiver was valve and not transistor. I'd already spotted the four 6L6 tubes, obviously in the output part of the circuit. Closer inspection revealed that the two output transformers were not identical, one of the originals had failed (or been...

About this site
http://tetrode.co.uk/about.html
I used to maintain a site www.thermionic.org. Principally to interest people unaware of thermionic devices (electronic "valves" or "tubes") in this excellent, if old, technology. Even in the 21st century there is much fun to be had and good work to be done with these devices. As I'm also interested in semiconductor based electronics (both analogue and digital) I have started this more general site which includes projects using semiconductors. This is an amateur website (in every sense of the word :) and ...

Auf den folgenden Seiten hier bei thermionic.de finden Sie vielfältige Informationen - wie schon aus der Navigation zu entnehmen - zu den klassischen DYNACO Audio-Komponenten bis 1979 sowie, später einmal, ganz allgemein zu Themen und Produkten rund um Selbsbau-Hifi mit Röhren und Halbleitern. Darüberhinaus biete ich Ihnen in allen drei Abteilungen die Möglichkeit, historische Bauteile, Baugruppen, Handbücher und auch vollständige Geräte aus Privathand zum Kauf oder Tausch an -.

The thermionic website
Welcome to the thermionic. Devoted to electronic valves [also known as tubes], valve radio circuits and equipment. This site is being built gradually, please check back again soon. This picture shows an 813 based Hartley oscillator transmitter being tested with a makeshift power supply. This transmitter was intended for the 160m (1.81-2.0 MHz) Amateur Radio band. You can read more about this project and some others on my projects page.

Thermionic diodes are thermionic valve devices
Thermionic diodes are thermionic valve devices. Saturday, February 2, 2008. Thermionic diodes are thermionic valve devices. Although the crystal diode was popularized before the thermionic diode, thermionic and solid state diodes developed in parallel. The principle of operation of thermionic. Diodes was discovered by Frederick Guthrie. The principle of operation of crystal diodes was discovered in 1874 by the German scientist, Karl Ferdinand Braun. And he was awarded a patent in 1883. US Patent 307,031.
