U67 pcb schematics

[ratrace]

Hey, i'm actualy attempting to redraw the different pcb for a 1:1 clone for my own usage (i got a nice neumann k87 capsule in a U87 poctop build and now i would love to put this capsule in a more historicaly correct build).

is it crossing the "line" to post this here ?

Do you mean you want to build a U67 with a K87 capsule?

 

[ratrace]

yes i would, corecct me if i'm wrong but i just need to connect the 2 backplate together.

Here is the capsule i got.

I am not a judge, nor do I make the rules. For me, the red line is when you use trademarks, logos and the like (and you try to sell this stuff). I also think that dealing with chinese product pirates who sell exactly these trademarks on industrially produced clone bodies is not okay. I also think it is wrong to advertise for them by presenting their links here.

I don't see any problems with your project, it's a DIY fan project for your own use without any intention to sell. Just my opinion of course.

To be honest, I don't understand what exactly you want to redraw. Someone PCB design?

yes, like the ioaudio U87/tlm67 mod.

Well, I'm not the right person to approve it. But, isn't it more exciting to design your own PCB inspired by the legendary vintage one?
I presume you have the original body and corresponding mechanics. You will need it if you want to go that route. Right?

I don't have right now, but that's the plan to collect mechanics parts over the time, you are right.
I also had in mind to buy your BV12 recreation for this build.

I have a TLM 67 that I will be converting to a U67. My plan is to create PCBs that are very similar to the Original U67 PCBs.

My thought was to learn KiCAD and share my progress here in case anyone else wants to do the same.

The pcbs with the original layout is straightforward. But what is the plan for the high impedance section? If using a diy body.

has anyone succeeded at recreating the original pcbs? I've contacted a member here who has OG format boards but he hasn't responded. Would be interested in purchasing.

I can help you with the layout of the PCBs

.
Works perfect with Moby BV.12. I don't know how transformers from other producers will fit.

You have a board for the RF filters? Do you have a source for those caps? I'm interested in your boards as well.

 

[C12VR]

WOW. gorgeous to boot.

I have a board for the RF filters as well. I bought mine from ebay but I think theres a thread here at Group DIY about those caps.

I have, I'm planning to produce a batch and sell them.

That might be copyright infringement if the microphone PCBs are a direct copy.

their patents and MWR on these designs expired years ago i think? the only thing they have legal precedent to C&D over is their registered headbasket design.
