New u87 Body

[kingkorg]

Very satisfied with it. Seems to be of the right dimensions, i don't have an 87 currently to confirm. Here it is compared to Behringer B2. Don't know if it's available on Aliexpress.

Looks much better than the Behringer microphone. Almost Neumann like.

Here's the thread with images of B2 vs u67.

A while ago I posted some pictures of two different versions B-2 Pro (not B-2 which was cardioid only), along with a U67 for comparison.
It happened in a feeler thread regarding useable bodies for poctop's DU67 PCB. It seems that thread was removed altogether.
Last week a fellow member PM-ed me to ask if I could re-post the Behringer pictures.
It was a selection from quite a few pictures I took and I'm not sure if this selection is the same. But it should give an idea.

Interior pictures next.

I'll concede the Behringer mesh reminds me a lot of Borris Carloff's head in Frankenstein
but then again having non parrallel sides might cause less reflections inside the headshell.
Ive used both B-1 and older B-2 as a basis for tube mic conversions and am vey happy with the results , I know some wont want their mic to have a Behringer logo on it ,but as its engraved not much you can do appart from fill and paint the outside . I'll live with the fairly nice quality nickel plating and funky headbasket , if anyone makes dissparaging comments on the logo I give them a look inside and they shut up fairly quickly .

I found this video. I don't know what about he talking. Also i can't find this mic in shops. But on YouTube at least 2 different video about it.

Temu (Shop from the video) sells promotional goods with limited quantity. When gone, gone.

The regular price was just under 30€, this super low price was valid only once for new customers .

Beautiful. Does it fit the Poctop boards?

No idea, sorry.

And that’s just a jewel where the switch opening would be on the front?

I got a free $100 U87 on Alibaba once because I asked if it had the switch/hole in the illustration photo, but it didn’t. I screenshotted the conversation and sent it to Alipay and they refunded me. Ask specific questions with Ali vendors.

There's actually a hole there, and purple ring under.

I have tried this donor body. It does fit Danny's tapered boards, but also had a bad resonance in the 100Hz + range that was noticeable/sensitive with any movement. I haven't had this issue with other donor bodies. Same dimensions as a Neumann

Haven’t tested it against much but it is better than many of my cheap mics!

Interesting. Thanks for the info. Do you think this resonance could be countered with some sort of deadening material to reduce internal resonances?

Don't know if it's available on Aliexpress.

Now there is https://it.aliexpress.com/item/1005....0.0.5b6118fcF3nfgG&mp=1&gatewayAdapt=glo2ita

I'm interested in that too @egoservant did you manage to fix it?

I also acquired from Aliexpress. I didn't have any luck with dampening. I only tried neoprene, but I got a real tire-shop vibe with that lol

I also have the same body and can report the Fuchs 87 boards fit perfectly in it, but also I have the resonance issue. I tried some self-adhesive rubber strips on the inside of the shell, but mostly the resonance seems to be coming from the headbasket, or probably more accurately, the capsule deck and the rails and the headbasket combined.
I tried damping the underside of the capsule deck. I tried zip ties on the rails to stop them from vibrating but so far, nothing I've tried works.
However, overall I really like the body a lot.

For resonance dampening, in some of my microphones I have used Isodamp sd40AL 5 mil aluminum constraining foil. It's pricey stuff but it can be purchased in small sheets from www.percyaudio.com. You can download their catalog to take a look.

Just to add to my observations about the resonance of this body. When I tightly grip the mic around the ring at the bottom of the headbasket and tap the body, no resonance. If I grip the top of the headbasket so that I have thumb and forefinger holding the structure rail that goes over the top and holds the mesh in place, no resonance, so I'm currently inclined to believe it's this headbasket rail that is the culprit.
