- The impact of feedback on internal overload;

- Stability of feedback amplifiers;

- Feedback, speed, and the difference between delay and phase shift;

- Positive feedback and its effects;

- Simultaneous application of positive and negative feedback in a 1950s tube amplifier;

About the presenter:

Jan Didden has spent most of his working life with the Netherlands Air Force and NATO, and in that period wrote many audio design articles for the audio press. After his retirement, he finally found time to finish all those accumulated projects. At present his main interest is on error correction in power amplifiers, which leads to unusual designs. His latest design, the paX power amplifier, was published by Elektor in 2008. Since a few years Jan also publishes Linear Audio, a unique, six-monthly bookzine dedicated to technical audio, with articles written by internationally recognized audio design experts.
