margan : non switching class B

[bambo]

NSB

Exactly Marcel,

for that reason we in Holland might better call it class nsB 😀 And, I agree, some may rightfully disagree as the same acronym applied for the fascist faction of Holland in WW 2.

Happy new year and all the best,

Mark, if I may intrude - Margan's idea seems to be good - but can we see even one amp utilizing his idea - built and tested?
Or at at least working sim of a practical amp, with decent numbers showing?

See figure 2 of the article that post #1 links to.

Could you please post your class B amplifier's schematic? That link doesn't work here.

I don't remember what article sreten linked to.

I don't remember what article sreten linked to.

I think it was the one from 1986 mentioned here: https://www.diyaudio.com/community/threads/margan-non-switching-class-b.122007/post-1932378

That's a Wireless World/Electronics World article, so you should be able to find in the archive mentioned in post #23.

Thanks! It was 1996 actually...but damn, I hardly see anything more complex today...Kendall's class I comes to mind being around the same level of subtelty.

Those screenshots are for my amplifier, not the one from E. Margan that sreten linked to in post #1.

Which is exactly what I asked for.

Right. That wasn't clear to me because you replied to a post about figure 2 of the article linked to in post #1. Anyway, nice that you found what you were looking for.
