Rudolf Moers was born in and grew up near Eindhoven, currently living just 300m from the still existing facility where Professor Tellegen of Philips invented the pentode in 1926. At his tender teenage years he constructed his first radio as well as his first amplifier, of course with electron tubes, but without much understanding. That came later after finishing Technical College. His first job was at a small company were he was the only electronics designer and learned practical hands-on engineering from the technicians. The 'technological ceiling' of the small company forced him to jump to the famous Philips company without technological ceiling and with a lot of possibilities for additional studies which he consumed in abundance. As a circuit designer he worked several Philips departments in Compact Disk mastering, analog video processing, CD/CDV-testequipment, medical equipment and electron microscopes. Nowadays he designs the electrical infrastructure and electronic hardware architecture of one module of the hugh and complex ASML chip manufacturing machines.
In these fast and hurried days, the ways and methods of electronics design are no longer relaxed nor unprejudiced. To continue this enjoyment of circuit design and construction, a decade ago Rudolf re-started his long-time hobby: tube electronics.
Rudolf has published earlier articles in Linear Audio related to finding the lowest distortion solution for an ultra-linear circuit. However, on closer examination it turned out that his solution...

TWhen Rudolf Moers discovered tube amplifiers, he could not find a good book that explained various concepts like the Ultra-Linear circuit, from a theoretical as well as a practical perspective....
