Considering that you have a very early U67, judging from the head assembly......
Thank you Klaus.Is that good or bad?
Maybe I'll look it at eBay.
I think I can replace the capsule myself, because I cannot find a specialist in Moscow.I will solder two wires as far as possible from the capsule.Or there are any subtleties?
Сan it be installed on either side?
Hello.I replaced the microphone capsule.I took a capsule of the new working U87AI.
To my knowledge (Klaus can confirm), the K870 and K67 are identical.
If it IS a true K87 we're talking about, the difference between the K870/K67 is that the backplates on the K87 are electrically insulated from one another. I'm not sure the difference that would make in a U67, but I bet Klaus knows.
Dusk,I'm afraid I must disagree with your advice to go with a re-skinned capsule as a cost saving measure. Re-skinned Neumann capsules represent, to me, a very poor value in comparison to a good Neumann (original) capsule, even if the fully-original Neumann capsule is more expensive. I have never heard a re-skin that sounded "right" or even especially close to it, even by the "best" re-skinners.To my knowledge (Klaus can confirm), the K870 and K67 are identical, so there's no reason to act rashly.If it IS a true K87 we're talking about, the difference between the K870/K67 is that the backplates on the K87 are electrically insulated from one another.

Brad,I didn't realize that the K87 and K67 were acoustically and physically the same capsule. (...) I was left with the impression years ago that they were different capsules.
Brad,I didn't realize that the K87 and K67 were acoustically and physically the same capsule. All else being equal I would agree that one should go for new (or NOS) when possible, rather than a re-skin. I was left with the impression years ago that they were different capsules. OTOH, I think you should listen to my reskin before dismissing the value of the service. I have two otherwise original 67's, both of which I certainly can't tell apart in a blind test, when comparing the capsules. I have had a few other engineers comment on this too. I seriously doubt even few could tell them apart.FWIW, for some capsules its a moot point anyways. For the CK12, KM5x series, M7, etc) it's either re-skin or throw it in the trash.
Sounds interesting, Dusk. I wish I was close enough to you to hear it.I've heard a Thiersch M7 reskin and a Drefahl K47 reskin. Neither of them approached the sound of a good original. In one case (I won't say which), it was on a mic that was a candidate for purchase, and was so obviously inferior to expectations that ensuing questions revealed the reskin.

Who did the work? I am skeptical about claims that third-party re-diaphragming of Neumann capsules, regardless the type, would be comparabe to a healthy original. The closest (still no cigar) that anyone has ever come in my estimation is Siegfried Thiersch's nickel diaphragms for KM54/56. His Mylar and PVC work, on the other hand, I found not up to par to the sonic quality of Neumann capsules/diaphragms.
