The Otto Schade method - A practical design method for rectifier circuits

The Otto Schade Method – A practical design method for rectifier circuits     Vol 8

Rudolf Moers

When someone who writes his own tube amplifier book because he is not happy with what is out there turns his mind to the mundane topic of power supplies, expect a very detailed and insightful article! Rudolf build on work done in the mid-20th century by Otto Schade and presents detailed graphs about transformer/rectifier operation, both qualitatively and quantitatively. Numerous graphs and measurement reports extend the readers’ insight in these matters, often for the first time putting a factual basis under existing ‘rules of thumb’, or showing them to be incorrect. For the designer, this article gives clear guidance to the selection and specifications of power supply transformers, rectifiers, chokes and reservoir capacitors for tube amplifiers.
