Oh there's plenty original (and some interesting variants on established concepts like using pole-zero compensation in audio amps which is rare) but as ever it's the client's copyright.

--- I don't think anyone's asking you to infringe copyrights, what you never seem to do is post simple schematics of your contemporaneous designs which would provide solutions for querents here.

Except I wouldn't want to post non-proven designs. And discrete stuff (one of my strong points) does tend to need proving.

Graham

Thanks for the links Michael. Little question: if I use this type of circuit with a symmetrical power supply do you think I can remove C7 (if the Q6 collector is at 0v)? Then how can I manage the retro-action (R7/R4) ?

There was a whole shedload of my circuits on the studiomaster site but some clot handed them over to a pay site.

I must mention that to the MD, was talking to him earlier.

Sorry, I meant to ask if he ever posts original circuits.

Doesn't matter what the capability of the drives are; all the load sees is the voltage it sees.

Your favorite ancient complementary bipolar class AB stage seldom has symmetric output current capability; again, it doesn't matter if the load is driven properly.

Any one have a violin to play, I've broke mine listening to Graham.

Build yourself a complementary output stage. The you can change the quiescent current from A though AB to B and finally C and HEAR the difference. AND yes, it can be DC coupled.

It's also by FAR the 'best' configuration audio wise and as efficient as it gets.

Graham

Wel, aside from 'obvious circuits' prior art et all what do you expect ? But I have no intention of giving away my design tricks publicly to the Chinese.

Graham

that affects any

You're not thinking clearly dV/dt = I/C

Graham

Really ?

And what is 'properly' ?

If Studiomaster hadn't shut down free public access to their schematics you could see loads of them.

Graham

Really.

It gets the voltage waveform the designer intended that it get.

John

Not to any extent worth worrrying over.

And you think that's about "if the load is driven properly" ? Don't leave your day job would be my advice.

Graham

Why would he want to? He designs high power amplifiers for medical equipment that you couldn't.

My day job is designing electronics. About $200 million or so of it, so far.
