Neumann M49 Clone : Build Thread Puck Style (TLM49 Conversion To M49 b-c)

[Murdock]

Did not change any circuit or components. I specially soldered a wire for testing. only needed to adjust the position of the 7PIN male pin according to the wiring sequence of M49C.

What kind of body is that? Can you please share a picture of the whole mic?

OK, that’s what the body is like.

 

[donivan]

is there 60mm of interior width for Dan's round pcb

 

[Murdock]

OK, that’s what the body is like.

Thanks! Can I ask, where you got it from and how much it cost?
And was the connector part of it?

Do these power supplies still have a 7806 regulator + diode for the filament voltage?
(Effectively producing a voltage of 6.7 V...)

Thé PS-2 does have a 7806 regulator.

I can’t comment on the PS-3.
But maybe @egroys & @ZHOUJUN can tell us more ?

Indeed it is a 7806!

I think the picture shows a vintage M49

No, definitely not. The bottom bell is different if you look closely.
Also, he told me these are new manufactured bodies. Sadly not available.

Ok…
He posted another picture which clearly shows the guts of a vintage Neumann M49, that‘s why i though the body is vintage, too.

Nope, that’s also not a vintage M49…
Compare it closely to pictures of originals online.

That’s the same mic as in the other picture. He’s send me another picture of the same mic and it’s clearly not a vintage M49.

Maybe… to me it looks quite similar to one of the M49s i repaired some months ago

Not maybe. Look at the plastic pillars where the capsule connections goes. Neumann always used transparent acrylic material (Perspex).
This new body uses some kind of opaque plastic.
The solder tags are also bend by hand and fastened with rivets in this clone. Neumann used Niet Lötösen (don’t know the English word for it).
Also it seems the body is made out of aluminum instead of brass like the originals.
And like I said, Zhoujun himself told me that it’s a clone body. He had to install all the components himself. That’s also why there are these old resistors and caps because that’s what he bought. They are not part of it.
Don’t get me wrong, it is a nice clone but not an original.

I'm working on something similar

The upper body on the right is from Aputis. But from where is the one the left? Looks like the XLR version from Jenny as there are no screws visible.

Yes it is early prototype on the right. Jenny's basket and mesh alignment is really nice I will make a new connector and some other mods to look better.

But the body is made out of 3 parts, right? So bottom bell, shell and basket? How do you intend to fasten the shell and basket when using another connector?

We will solve it, but only next year!
