John Curl's Blowtorch preamplifier

Re: Re: AD797

1 and 3 make sense, I need to be at work since I don't have a copy at home. Sometimes clamp devices get drawn in a way that makes no sense.

I would really appreciate if you shed some more light on the purpose of Q50, but take your time, please.

Regards,
Edmond.

Measuring the S/N would be difficult, but the car, itself, is pretty quiet, AND we just came from a listening room with Wilson Grand Slam or some such speakers, huge amp, and primo CD, and we thought it disappointing! Go figure.

Wait till you are approaching 80 years old, Scott, before evaluating the Bentley again.

@John,
Anyhow, you had a nice day, great!

Jack also bought me lunch at a fancy restaurant. I really appreciate fine food when I am given it to eat. I can't afford it myself, but I know the difference. It is the same with hi end audio quality, in my opinion. If you can't afford it, or just not justify it to yourself, it doesn't help anyone to condemn it as a rip off.

That about says it all, my mother still works at 85, she has run her own business since she was 18, hairdresser. Now she mostly does cadavers, her former customers.

Hey, I want a Boxster, like my other business associate with Jack Bybee. Jack has owned just about everything over the many years.

Well, Grey Poupon is very affordable .

Obviously, not enough Bybee devices. You and your business associate Jack should know that much.

I think this is a very poor example. I believe that you are referring to spread spectrum clocks being used to to spread clock harmonics over a wider than usual spectrum in order to pass the FCC emissions test. Any decent spectrum analyser available in the past 20 years (apart from the cheap garbage based on tv tuners) can see this effect.

The spectrum anlyser is NOT at fault. The FCC test is based on the average signal level in a narrow sweeping band. This is not an example of inadequate equipment but of an outdated mandated test regime. Or rather a perfect example of commercial greed leading to some clever design methods that satisfy the letter of the law while comprehensively breaching the spririt. [/B]

No need to be so defensive. And you did illustrate my point that the analyzer can be fooled if you know what its looking for. Conversely that shows that you cannot know that it will see everything that is there. The FCC receiver with its quasi-peak response won't necessarily show the actual energy coming from the clock of the spread spectrum source. The knowledgeable operator is aware of the effect. The product meets specs and passes FCC, but could cause more interference that one that has less RF but reads higher on the receiver.

The core point is to understand the limits of your measuring instrument. They all lie, mostly in predictable ways.

Grey Poupon on my hot dogs, is a little too much for me. I prefer enhanced yellow mustard.

 

[john curl]

That's EXACTLY what it sounded like!

 

[syn08]

Look at DDS output by spectrum analyzer. 3D view would help a bit.

Or look at the GMFZ output by spectrum analyzer, it will show the same thing.

Please stick with audio, unless you want too really be embarassed. Just ask SY.

Horses for courses, mustard for the right occasion.

 

[PH104]

Maille for Dijon.
French's for yellow.
Frank's Mr. Mustard for a little kick, Lusty Monk for a little more.

And........
English Red Mustard
This recipe comes from Mount Horeb Mustard Museum. If you want it really hot, use piquin chiles.

4 tablespoons cracked brown mustard seeds
2 tablespoons Colman’s dry (powdered) mustard
1 teaspoon salt
3 small dried hot red peppers, crushed (Or to taste. Chipotles are good too.)
1/4 cup cold water
1/4 cup beer

Whisk together the dry ingredients in a small bowl, then whisk in the water and beer until the mixture is smooth. Cover and refrigerate for 2 days, for the mustard to thicken and "ripen" before using. Store in a tightly covered jar in the refrigerator.

Yield: Approximately 1/2 cup
Heat Scale: Hot

and JC -- have you ever talked to Dick Sequerra about his spark plugs? I was surprised seeing them on his website.

 

[john curl]

I am a Founding Stockholder in his spark plugs. I believe!

 

[PH104]

thanks -- expect a contribution to your stock. I'll give them a try.

Dick Sequerra does spark plugs, Bybee overclocked hot cars. Cars and audio as fetish object it all makes sense now.
