The title says it all. Why? Why do so few manufacturers use them?

Hi Steve, Cost is my guess. Plus a few other things that might complicate the design. The output device(s) will see two different inductors. Regardless of their respective values it will introduce anomalies. The primary benefits would be to SE amplifiers. Then the dc power would not have to go through the output transformer. This would make it possible to use a much smaller output trannie as you would not be likely to saturate it. In push-pull designs I see no value as if operated within spec. A PP output transformer should never saturate.


Good Listening
Bruce
