John Curl's Blowtorch preamplifier

Joshua_G I have used this design of yours as an example of good audio design.
I tried for months to come up with a better design than this for the new Vendetta phono input stage power supply

Dear John

Do you think that Joshua came up with the last "design" by his own, or did he get some "blessed" support?

BTW "Happy New Year"

Music signals are all complex ever changing transient draw situations that require perfection across the board under any and all complex transient loads.

Beyond basic stability and noise issues, the results of any possible linear or constant draw measurement is entirely irrelevant.

So?

Could you please try to explain one more time?

Mr. Andersen explained this long ago .

I don’t argue about that, but just would like to know why he answered that to the post by Syn08.

So?

Specific and or lowest levels of ripple or regulation can be almost irrelevant and many times, if taken to an extreme, without this coming particular point as the first, on order of importance....can make a real mess out of the sonics of a given piece of audio gear.

That's all I was saying.

I mean, the last thing you want is secondary modulation of your transient signal components (where the ear wants to be-and hears by) by any regulation devices.

One reason that large devices (T-03) as regulation might work better, soncially speaking. This is partially due to low levels of temp-co shift under transient draw due to the greater mass...the downside is a noise that tracks along with the signal which might be more sonically annoying to some....

Yeah, I hate when that happens.

 

[syn08]

Specific and or lowest levels [...] sonically annoying to some....

 

[andy_c]

Yeah, I hate when that happens.

I know what you mean!

But the real question is, "does the Heisenberg Uncertainty Principle apply in a chrono-synclastic infundibulum?"

 

[jan.didden]

Decisions have to be made according to the circuit which the regulator feeds.[snip]

It's not a regulator. Can we at least remain honest here please? Communication is already difficult without changing the meaning of words indiscriminately.

I’m concerned about the reputation of JC, and that you are taking him with you in to the mud.
Like this thread has become he must answer for himself and also try to support you.

If you had any respect to JC you wouldn’t post whatever you came up with and expect John to support you.

It seems like you don’t have any respect at all to the people you are posting with, I don’t like that kind of behaviour. I respect JC, and if I didn’t respect him and his work I wouldn’t argue with him and I think that is the same with everybody else in this thread.

Stinius

Stinius,

Thank you (and Syn08 and SY) for clearly stating what many of us must think.

Jan Didden

 

[Joshua_G]

I do, yes. He's a good friend. Which is why, even though I learn stuff from him and am delighted to use ideas of his and bounce mine off of him, I don't use his name to try to enhance the credibility (such as it is!) of my work.

If you think that this is what I'm doing, you are wrong.
At least, this isn't my intention.

 

[Joshua_G]

Well, surprise surprise, I do. But respect and truth do not necessary overlap.

1. Yes, respect and truth are not synonymous, however, what do you mean here?
2. What is being reflected in many of your posts here is the opposite from respect to JC.

First:
Why don’t you just use your first circuit?

When low output Z is more important, I will use a modification of my initial circuit. I'll post the modification later.

When lowest noise is more important and when the load draws current of the same magnitude all along, I'll use the last circuit.

Please explain what you refer to as "mud".

Please explain, what do you think I shouldn't posted?

Your assumption is wrong.

I don’t like that kind of behaviour.

What behavior?

Dear John

Of course the circuit was changed according to John's suggestions – which is why I don't give myself credit to the circuit.

You see, I'm interested in the best circuit to suit my needs – not in credit.

I came up with a circuit, following John's suggestion and putting some of my own ideas. Do you find anything wrong with it?

 

[Joshua_G]

It's not a regulator.

Indeed – it's a kind of gyrator.
However, it supplies very quiet power.

 

[Joshua_G]

Stinius,

Thank you (and Syn08 and SY) for clearly stating what many of us must think.

Is it a coalition of those who constantly attack JC and some of his ideas?

You people seem to be very good at verbal arguments.
I'd love to hear amplifiers you designed.

Which is why different supplies will be better sonically to different circuits.

I'd love to hear amplifiers you designed.

I've published several of my designs, with a new line-stage article to appear shortly. You're free to build them and draw your own conclusions.

Joshua, stop, you are killing me Do you have any idea what a gyrator is?
