MK67 - new U67 clone coming up

[JessJackson]

Excellent project Max.  Another vote for the resizing the PCBs for the TLM67 housing when you can, I would commit to buying that.

I own one of the very limited run of 67 re-issues that Neumann did in the '90s, let me know if you need anything.

Cheers,
Ruairi

yes please could you take high res images of the insides from all angles?

Sure. I am just surprised. There's more people than I would have thought interested in that avenue. I would also go that route if I had more money!

Myself? I will go with chunger's SYT-5 body. Unless Max makes a U67-clone body...

 

[Le Roux]

Where are these TLM67 bodies available?

Another vote for Max making a mic body. The MKU47 is fantastic!

You buy a TLM67.

and I'm really interested as to what coupling cap they used on the re-issue as the original dry electrolytic Siemens and Halske wasn't available.

I would also be interested in a tlm67/u87 sized version

Cool.  Pics when I get a minute.

After taking some measurements, this is the U87/Tlm67 to U67Pcb.
Like the original, the capsule socket houses the hiZ parts.

Superb Max, thanks for doing this. 

Life is busy but when I get to build one I can do very direct comparisons with my 67 and report back, I expect good things.

 

[JessJackson]

Max, nice..

Looks like your missing the bottom board that sits inside the lip of the bell with the pass through filter caps on it.

Theres also two metal pins that stick out of the railings to stop the top board board from sliding upwards. Other than that I found that without the bottom board in place when sliding my housing back on and off it would get stuck as the pcbs are able to move downwards a couple mm. I will send you my exact caliper measurements later today.

It looks like you may have one too many components in the high z section.

I tried to reach out to you on email so we could work on this together.

Thanks Jess, but i got all the measurements and details. I'll also receive a Tlm67 for prototyping soon.
Also i just placed the 500pF in the shell so i don't forget it (i know it belongs into the switch housing, which i did'nt draw)
My Pcb is held in place with the transformer clamp as shown here:

Max your sick with those 3d renderings. My hat off to you for that learning curve.

cool. yeah the metal that comes with the u87 is a lot bigger would need dremeling and drilling in order to make work.

What about the lower filter board? U gonna leave the filters out like i did?

J

 

[ioaudio]

Thanks J!
Yeah, i leave out the feed-through caps on the bottom, since there's enough filtering going on on the rest of the circuit.

Hi Max,

Are the MK47 kits (without the body) only available from the states now? 

B

 

[ioaudio]

MK47 Pcb kits will become available from me again soon.

 

[Edward]

When is this U67 kit becoming available?

My bank account won't like it but this is what I want to build next..  ;D

 

[ioaudio]

Initial testing of the proto looks very good, i ordered the first batch of pcbs and parts.

-Max

 

[Edward]

Thanks Max. Very exciting!

Will the kit include a PCB for the PSU as well?

 

[ioaudio]

I'll collaberate with Chunger - PCB, mic body, PSU and probably the capsule will be included!

I'm in for one when they're available
