Few links, none relates to specific design schematics.
If you have a schematic you want us to look at, please post it here.
It is schematics on his home page.
Pretty good ones as well. 🙂

You must realise that IC means Interconnect. PC means powercord.
Realized now.

After re-reading, explain to us why what happens "outside the box stays outside the box"...why we really don't have to worry about multiple ground paths destroying the shielding.
Concerning design of audio amplifiers, in relation to what you wrote, basically there are two measures that can be taken:
1. Separate mains ground from the audio ground.
2. Take care of proper input and output impedances.
Good case shielding is another measure, however not directly connected to the problem you raised.
Also, good interconnects are important.

Do you think about the picture I'm thinking about?

Um, the one PMA posted..the wire routing design rules must have been set to "al dente".
It does seem to be that way, no?syn08 said:Really, I don't mind your JC adulation and I'm sure JC doesn't either.
It don't matter none to me...everybody's got an idol or two.
'Sides, this is a thread about JC's design...gotta 'spect some idol worship..or, at the least, respect..
Cheers, John

C'mon Josh, can't you find the schematics in those threads?Wait, they might be to large?
In all those links there are quite few schematics. If you want me to relate to one of them, please post it here for me and all others to see what you are talking about.

Did you come up yourself with the knowledge you have, or did you have any teachers?
"Um, the one PMA posted..the wire routing design rules must have been set to "al dente"."
Yep we are thinking of the same picture😀 😀 😀
JC has stated that he had nothing to do about the layout and the final result, I belive that is true.

Josh, I have no interest to further pursue this. I can't force you to see more than you want to. Happy holidays!
I apologize for the misconception. I should have been clearer..Joshua_G said:Realized now.

1. Given the National Electric Code on this side of the pond, complete disconnect of the audio ground from the mains ground is not a possibility.
2. Proper input and output impedances is a circuit design issue, that is not what I speak of.
Shielding case or boardwise, is certainly an issue. It can alter how the return currents flow.
Do you have a layout to show us so that we can "pick apart or praise" the layout? I note you have asked others to show something or go away, I ask the same of you..
Cheers, John

I have no reason not believe John Curl, however, it looks like some people are very happy mocking greatness.

It would appear that the initial teachers I had are all dead..

Much of my current knowledge base I had to learn on my own, much of the inductance stuff, magfield goop, soldering, epoxy, semiconductors, on the job training.
Some of what I know is a result of being the first to do it. That is actually a "perk" of my current work environment.
Some of what I know I learned from the best minds in the world. Co-workers among them.
You seem unhappy with the term idol worship. If you re-read my post, ""gotta 'spect some idol worship..or, at the least, respect"" is not derogatory.
Cheers, John
Joshua_G said:If you have a point to make, please support it by a schematic posted along your post.
Thank you, email received and file downloaded.
As I said. This topic is discussions about John Curl designs and ideas.
So I respect this.
People do not read this thread to see my ideas.
I can post my opinions and thinkings on this topic for what it is worth.
regards to joshua
glad you got that curl material from my link

However, this thread is all about good circuits design.jneutron said:
2. Proper input and output impedances is a circuit design issue, that is not what I speak of.
Other issues will find more proper abode in other threads.
No, I have no design of my own, I'm a technician, not an engineer. However, I have enough knowledge to appreciate a good design when I see one. Me asking others to come up with a better design was to those who criticized John Curl's principle design.jneutron said:

It is good that there is someone to praise someone.

You seem to assume reading my mind.
Only you can possibly know what you meant by idol worshipping and what motivated you to bring it up.

And I respect your respect.
However, it seems to me pointless raising issues in this thread without directly posted schematics to support those issues.

Thank you again.
It is both my pleasure and my benefit.
It is very simple. It was my response to anothers use of the term adulation with respect to attitude towards JC.Joshua_G said:You seem to assume reading my mind.

If you have changed your name to syn08, let us know..that way there will not be confusion when you respond to something I say to him..
Have a nice weekend.

Not all that seems to some to be a confusion is actually what it seems.
john curl said:Joshua_G, I have to put up with this over the years. Thanks for your input, however.
Thank you, John.
I believe I'm quite aware what you had to put up with – and I respect you also for this.
Remember, I read this thread from page one … and also elsewhere.
Anyhow, I'm here to learn and I learned a lot and I keep learning. I don't mind much all the side stuff. If anything at all, it exposes where some people are at. It isn't very likely that I'm going to be maneuvered to be where I don't want to be.
Joshua_G, another approach would be to attach the output resistor to its respective input, rather than ground and drive through the gates, rather than the sources. This would give a small amount of negative feedback, BUT it would be very fast, and essentially local feedback. This might be the easiest and quietest approach.
