Hi Jocko,

As you know I can not find the schematic & b.o.m., anyway was to compare with Erno's series reg.



Erno's regs. are very good only 5uV noise

Excuse me Jocko but what do you want to tell us in your rants? A highly trained professional which can't manage to draw a schematics? You must be joking, right? So if this is a joke, what do you want to tell us and why?

Oh, I assure you that I can. I chose not to. Punks like you giving me crap is one reason why I will not.

Jocko

Good to know that you are quite normal but I still wonder about your public statements. Why?

I would have thought by now it is obvious.

BTW, it took you 18 months to make your first post, and that is all that you want to know? I would have thought most people come here to learn stuff, not tease the 800 pound gorilla in the monkey cage.

Whatever, dude..............

What? I am supposed to be a walking compendium of every other designer's work? I have no idea what he does, and no desire to find out. All I can tell from that picture is that he uses a lot more parts than I do. Whoopee!

OK...............5 uV............is that broadband? At what frequencies? Numbers without context have no value. Haven't I taught you guys anything?

Maybe it is time for me to ride off into the sunset.......

Output noise over the audio frecuency range is less 5uV.

That's the reason that I want information about your regs. because reading your post I see that are several common things between your desing & Erno's design (series reg. topology, NE5534 op-amp) only was curiosity, you have your regs & I have Erno's regs. no matter, no discussion, I only want to learn if you left me, like Erno's left me when I asked him to learn.

Erno is out to make money. I know that I am not going to make any. I just don't want to have to pay for the privilege of doing everyone's work for them.

Which is the direction this has been taking, since the days of that other forum. It has only gotten worse.

Ok..........here is something to ponder:

Designs like Walt Jung's use the output to supply the error amp. But what if you don't have that kind of headroom? Remember, this was intended for some battery-operated gear. (Just worked out well enough for other applications.) You have to power it from the "raw" supply. Which, being a battery, shouldn't have all kind of hum and ripple issues.

But.............let's say that it did. What about PSRR of the error amp? it kinda sorta follows the OLG. What do you have to do to the supply line?

Have you even remotely considered that Jocko has free will to do whatever the heck he wants? I'm sure he's drawn a schematic for his widget at some point, he just doesn't want to share the thing with the world.

I deal with the same question almost monthly, professionally. Customers frequently ask for schematics of equipment that I've designed. We'll say no, and the customer throws a hissy-fit. I've got plenty of reasons NOT to give out schematics:

- The whole "trade secret" thing.
- The customer doesn't need them to operate the equipment.
- It requires time and effort to publish them along with the associated parts lists, etc. Sure it's not a LOT of time/effort, but if I don't have to, I won't.
- It encourages the person to take the thing apart, change stuff, break stuff, etc. Which leads to time/effort on the part of our customer service staff after they've broken the thing in an attempt to tweak it.

Reasons TO give out schematics?

- Allowing people to understand better how your equipment works, so they're more comfortable owning it - informed customers can be happier customers. I'll give relevant information to inquiring minds, but not in the form of a low-level schematic.
- The good feeling of letting out-of-warranty customers repair their own equipment... for the non-existent base of customers who own a BGA rework station and know how to work with 0402 surface mount.
- Umm... don't have any others.

No, really............I haven't! Ever. Not at my real job, and it carried over to my hobby. The bosses were more interested in all of us making money for the company. Taking time to make documentation is time wasted that could be spent making stuff that worked and made money. If it broke and needed fixin', then we screwed up and were expected to make it not break the next time. Besides, we were a rapidly growing company, and stuff usually did not stay in service long enough to break.

So there. (Not gmarsh, the rest of you.)

The man does what he wants with his work, shares what he wants and says what's goin' on in his mind.
I don't see any problem with this.

About the rants, one thing that some don't understand is the Texan humor. [joke]
Look better and you'll find some brilliant stuff there.

Sorry everybody, I believe that a forum is the way to share: so the people to know teach & the people like me try to learn, so I am really confused about the sense of this forum. Everytime that in others spanish forums or DIYaudio somebody ask something & If I can help I give the information because mine point of view is that the DIY spirit is share/help/compare etc.

But if it's not the sense of this forum, please be so kind to let me know wich is the sense of this forum: several people having/sharing/helping between thems & other part of the forum don't count, so it's no sense, will be better to do a restricted or closed forum with no public access.

I can't suscribe to a forum to copy & after sell the information to the commercial market.

Sorry in advance, I can't express very well all I think because English is not mine natural language (I'am Spanish).

I don't think that anyone here suspects that you are like that. There are some who are, but let us forget about them for a while.

Teaching is one thing. Demanding and expecting is something else. I have been experiencing too much of that lately. People getting irate when I don't have the time to give them personal instruction. Some others like to snoop into my private life.

This section of the forum is designed to be different from the rest of the forum. It is designed to be about things that interest me personally, and what I care or am able to share (in terms of physical items). So, don't get the wrong idea about the forum because I am not interested in proceeding any further in dealing with people who have an interest in acquiring stuff that I have designed for my personal use.
