WebWikipedia WebMar 5, 2005 · The input section of the original Cary 300SE comprised a single double-triode 6SL7 operating in "cascode srpp"—half the tube is used as a single-ended grounded-cathode amplifier with the other half an anode load comprising a constant-current "follower"—to ensure low-impedance drive to the output tube grid. nightbeforetheexam.comWebAug 30, 2012 · Here’s the usual cathode-follower-power-amplifier design thought process: since—as compared to a grounded-cathode amplifier—the cathode follower offers a much lower output impedance (Zo), the output transformer’s winding ratio can be equally reduced, allowing the use of 500-ohm primary instead of the 5,000-ohm primary needed … npr fresh air stanley tucci

"WebThis circuit promises the advantages of both the Grounded Cathode amplifier and the Cathode Follower with high gain and low output impedance. Two tubes act as a single-stage, close to push-pull. The overall odyssey design is a fully balanced differential push-pull circuit able to direct drive the output stage. " - Grounded cathode amplifier
