The F-Word - or, why there is no such thing as too much feedback

In Linear Audio Volume 1, Bruno Putzeys wrote  The F-word - or, why there is no such thing as too much feedback. He addresses many issues related to the use of feedback in audio, as well as several misconceptions. The section on 'slow' and 'fast' amplifiers will be an eyeopener for many. He also traces historical events that puts us in the situation we are now. A critical attitude towards negative feedback is certainly healthy, and Bruno gives us the information to base our opinion on.
