John Curl's Blowtorch preamplifier part II

[anatech]

Hi ostripper,
Exactly!
Engineered to survive, just like everyone else out there who designs audio equipment. There are a few exceptions (technically speaking), but the most common designs require some isolation from unknown capacitances.

I'm going to bet you looked a the output with a 'scope after removing the output inductors too.

Perhaps a Skoda is your sort of practical 'compromise' and a Porsche is my sort of 'no compromise' design. It is not an impossible design, but a design with a minimum of performance compromises.
Are you trying to impugn my design reputation? This is what you appear to do constantly, and I think that it is to 'sell' yourself to perspective clients, if that is possible. It won't work, and I suspect that this sort of attitude has hurt your job prospects in Silicon Valley as well. They want team players as well as good engineers.
I would normally keep this to myself, but I think that you should know it.

Personally, you absolutely don't know what you are talking about. Your ignorance, and only your ignorance renders Porsche as a "NO COMPROMISE" car. Even for criteria the design had to met it is suboptimal, otherwise there would be no Automarket Porsche tuning shops. The same with audio. If you see some design to be a NO COMPROMISE that means you have no knowledge to see which criteria it does not meet, and how the design can be optimized

I see now; you are trying to put me down because of your jealousy, you think my existence here and my comments can lower your income of bread and butter. It is absolutely clear from your post.

Slip well, dear friend! There are lots of market niches in this world, enough for all of us, if to stop fighting ans start thinking. Also, sometimes it is good to read some basics about signals and spectra representations. It is the must for you, if you want to stop making fun of yourself in front of all worldwide DIY community, with your non-harmonic content, and Ducks on the picture.

I'm sorry everyone, but this is becoming ridiculous.
No matter what I say, it is twisted and turned.
If I mention Porsche, someone says RUF.
If I mention being called dishonest, it is denied by the very person who hinted it.
It is complete foolishness to use a 2 uH output coil, of any kind and design, unless you are interested in applying more negative feedback. We discussed this at some length, years ago. I have DELIBERATELY removed the output coil from my most recent designs for the last 20 years. It is not an ACCIDENT! However, I was not first to do so, as I recall, Nelson Pass did it long before me, and I suspect for the same reason.
Anatech, you really don't know modern audio design. I'm sorry, but you just don't know what I do, why I do it, or why it tends to get good reviews at even a relatively low price point/performance ratio. Please don't 'guess' what I think or why I do what I do. You are clueless. I think that it is because of your lack of an academic background in engineering. Just my opinion, of course.

No John, you stepped into something you just have no clue about. Plain a and simple.

Regarding electronics, you can beat me any day, but regarding performance cars, you're gonna have a hard time doing so.

So far as I am told, Jack Bybee's Bentley has more HP than a Kleeman. That's the car that we like to drive around in.
Jack's Mercedes is pretty comfortable, but it is chipped to limit at 155 mph, and that is about all we want to do around here. I guess that's why he went out and got the Bentley.
It is difficult to modify cars these days in California. It is against the law, and people get caught and fined.
Again: What I was TRYING to say is that a NOVICE should not try to modify a Porsche or a Mercedes, and I stand by my statement.
Can't anyone here actually understand what I put on paper, without flying off in some new direction?

Don't step in it

BTW, the offer on carbon is still on John.

ML It was 50 years ago, and I thought that it might increase the hp.

OK, I was just about to let you off the hook, but you just keep stepping in it.
650bhp, no, the Bentley does not push that much.

Even if it did, the brakes on the Bentley are toy brakes, not to be compared with the brakes of the Kleemann
