About :

Today's film section is about the first example of a pentode circuit. How was the pentode wired in an audion from 1946? It is an attempt to use the Telefunken-B4712GW radio receiver to understand the circuit that was implemented. I would like to take this opportunity to thank Mr Richard Kügeler and the Wiedenbrück Radio and Telephone Museum for their kind support. This project naturally has no commercial aims, but is an educational project. It is therefore not my intention to promote or advertise any products. No products from companies or organizations were provided for the project, but were purchased by myself or come from the museum. Looking back at earlier developments offers a unique opportunity to learn from old patents and to make them relevant to current projects and developments. All written contributions represent my own free opinion. Please note this to avoid misunderstandings. Technical errors can also never be ruled out (despite all care)!
