Hey Vinnie
Check Hagtech out. The link here is to the 1st one with the 12ax7's.
It is the whole manual. If you google around you might find the octal one he did, not much difference.
Have fun
Tom

Opps, I didn't know it was a commercial amp. Probably ought not be doing copies of it. Thanks just the same, I appreciate it.

"Still Working the Problem"
I was referring to the previous post about the coronet....
Schematic was posted on public domain many times also by Jim so I don't see why you can't breadboard and try it out. From myself I can add that it's nothing special really , rather flat and on neutral side of things , boring comes to mind no matter what component quality one use. Octal version is a whole level better sounding to the point where in comparison 9 pin Cornet sounds like mono. 0f course, it's better than SS crap.
The design I would recommend is EAR 834 with Thorsten mods. Runs circles around most affordable phono units- bass, balls and highly musical. Also Audio Note M3-M8 phono is a nice one ,not as dynamic but maybe more nuanced. On a general note my understanding is once the designer or manufacturer post schematic or design on public domain it means it's free to copy it for private , non profit use , no additional note required.

"I didn't know it was a commercial amp. Probably ought not be doing copies of it. "
Why not?

Same reason I don't copy other peoples designs unless there is a statement on the schem that says "it's ok to build one of these for your own use". Some folks mind and others don't.
"it's ok to build one of these for your own use"Of course it's OK. It's always OK. It's not as though designing a circuit entitles anyone to some sort of supralegal "first rights." You or I may not be allowed to publish a copyrighted schematic of the work, but that's an entirely different matter than constructing a working copy of the device for our own use. The latter has been done for centuries. It's the American way.

I agree with Paul that it is a moral obligation, if I understood his post correctly. Besides, even if it is the "American way", which I am not sure I agree it is, that doesn't make it right. If I designed a circuit I would expect people to recognize the intellectual property rights unless I specifically said they could make one for their own use. I also don't believe that pirating software or music for your own use is ok either.
That said, I don't think it would be particularly wise to post a schematic in the public domain if you did not want it used by others. Some people don't, they just put it in the construction manual.

This is not an intellectual property issue, and no individual has any such moral obligation. It's all well and good that we want to be decent people, but you two have crossed the line between respect and altruism. I've seen a number of good people - like yourselves - fall victim to the same misplaced sense of honor over the years.

And I have seen many people rationalize away what is the right thing to do because it does not fit what they wish to do. If intellectual property is not a product of someones mind, what the heck is it?
OK is not the same as legal. "OK with the designer" is a moral obligation IMHO; only the more egregious moral obligations become legal obligations.
Paul, help me out here. I'm trying to understand what you are saying.Does this moral obligation extend in perpetuity?
Even a patent runs out eventually and enters the public domain.
Look at all the manufactures making the pleated tweeter now that Heil's patents have all run out. Beyma, Mark & Danial, MartinLogan, etc.
Are each of them under moral obligation to the Heil estate not to do so?
I wasn't aware that even a standing patent prevented a person from making a design for their own use. I thought it only prevented them from making the design for profit?
I thought publishing a design (disclosing) before patenting a product prevents a patent from being obtainable?
Most of the published designs (setting aside the disclosure issue) would not be patentable in the first place since they contain only prior art.
A reshuffle of a bunch of old ideas is not (as far as I know) a new idea.
I know that the patent office hands out patents to anyone with a pulse these days but that doesn't mean those patents would stand up in court if it can be shown to be only prior art already in the public domain.
