It looks like the discussion went very far from D-class amps . Can we go back to it?
Drzhuang, are these amps used in any commercial products (especially in PA systems)?
Can they be purchased in China (for example in Beijing)?

This is the third time I have to split off-topic posts.
I've got a job that takes part of my time as well.
Or you guys stay on topic, or I'll close the thread.
You've been warned.

Yes, I understand you clearly. That "sorry" is for all who take care of the topic. But you know that the topic started in disputation. I can't answer you question here. Sorry. This is for you.

Sine wave, resistance load, DC current meter and DC voltage meter for power supply£¬ AC voltage meter for load. In rated output power get data then calculate.
