I think I forgot the Gerber files.
So here they are.

If you downlod the files in the first post, you should have PDF´s of the PCB´s.
As wel as a BOM.
Gerber is for production only.
We spend a long time tweaking the design, and believe that the design as it is now, performs just the way it is intended.
If we public the schematics, history shows that suddently the discussion is more schematics and technology than it sound and performance. That is one of the main reasons not to public the schematics.
However.... We will provide PCB-layout and BOM, so that anyone can build the preamp.

Hurtig I understand your concerns but after all it's a technical forum, more or less...

Yeah.
But last time we posted schematics, focus turned away from building.
We don´t want that to happen again.
But as such there is no secrets at all.
You can tell in short words
what this amplifier is about.
Opamp? Transistors? Output stage? etc etc
As Kurt and I wrote, the schematics wil not be public at this moment. Our goal is not to discuss schematics, but to achieve the best possible sonic performance.
At this moment we are very pleased by the sonic performance we acheived.
Anyone who feels like trying, can build the preamp themself. Quite a few DIY'ers here in Denmark did already, and the feedback that we get is very good.
For those more into dissecting schematics, this project really isn't the right one.

I think I did already do so.
But anyways:
It is discrete, bipolar, non NFB and with no caps in either signal path or powersupply - only 4 electrolytics for smoothing.
It features shuntregulators, DC servo´s, SMT and state of the art components througout.
A friendly observation:
hiding the schematic of a DIY project and simultaneously inviting people to build it is absurd (to put it mildly).
Many understand that as some kind of manipulation which automatically causes negative feelings towards a possibly good project. I doubt that anyone would take the bait...

Hey guys..!
I have a one great project too.....
Let's go and buy some good Pass amp.....
My goal is only to achieve great sonic result....🙂 And than we will discuss...
Sory Kurt....I cant resist myself.....🙂

I surely won't - I'm not in your target group for sure, barely have time to build my own stuff, let alone wasting it on this kind of.... 🙄
