Initially took my U87 apart to try and fix a dent in the mesh basket covering the capsule. Ended up getting sidetracked with the brilliant idea to clean the capsule. I've should've left this to a professional. Fortunately, I did not damage the mic. It seems to be performing no different than it has for the past 20 years.
If you're interested in cleaning your mic capsule a good video / tutorial to check out is FreddysFrets "Cleaning a Dirty Microphone."

People who like to know their gear inside and out have all been in one or two of these situations . Thanks for sharing this ! It will make me more cautious if I ever decide I need to clean some of my mics ,

Really useful posting.

@waytoowhat 2 года назад

Thanks for the video, did the same to my AT 3035, whiped more than half from the center. No difference in sound noticed but it bugged me to wonder why it sounds the same...

I feel your pain brother. Yesterday I did it with my u67 reissue... Good thing is that you can buy a used tlm 67 and just swap heads between u87ai/u67 reissue and tlm 67. Same capsules.

@manjulwalia1995 3 года назад

That's actually a layer of pure gold to allow electrons from the entire surface of the capsule to travel with least resistance into the silver wire. As seen in the video , some of the gold material from that layer is removed while cleaning but mostly is still intact. As a result the mic would work perfectly under normal conditions.

@manjulwalia1995 3 года назад

Also if the capsule somehow fails or not performing upto the mark , you can get replacement capsules. Original ones would be expensive as you know but there are OEM versions also and they are quite affordable.

@Allplaysful 3 года назад

dude can you please help me? my akg c414 TL II i just bought has aprox 50% of the front side of the capsule with gold, I have photos if you're intrested. you know if that might be related to high noise floor, and resistence to SPL... the sound i'ts ok except for the abnormal hiss.

@ronedwards8239 Год назад

Always use a pop filter & cover the mic with a plastic bag when not in use! I use a zip lock bag. (Those metal mesh pop filters still let water droplets through).

@dragonflythemusician 11 месяцев назад

Great guide! There's an AKG C4000B that is not noisy but sounds like a lowpass filter is applied to it's sound. Do you think cleaning might help with such a condition or you have some sort of advice for me? Thanks in advance!

Man, I’ve been there. Had to buy a brand new capsule from Neumann.🙂

I did the same thing with Neumann M149 😢😢

@Piplodocus 2 года назад

Thanks for the nice worrying video. It's all too easy to try follow videos of everything going swimmingly, then buggering it up yourself. Seeing people do stuff very worried makes me the right level of nervous. But I gather from the end of the video it was fine though?

@zeitakulobusta9708 5 месяцев назад

No offense but it looks far from fine - if I bought that mic used without any warning then saw this I'd be pissed.

Thanks for posting! Planning on doing the same to my u87. This issue was the qtip?

@portlandundergroundrecordi6396 3 года назад

Yes it was

@burtonjc 3 года назад

Was it the solvent that caused this or the pressure from the q-tip?

@portlandundergroundrecordi6396 3 года назад

think it was the pressure from the q tip...

Why does your circuit board say U89 if this is a U87ai ? It also doesn't appear to be a U87 board judging by several pictures of U87 boards I've seen online.

@portlandundergroundrecordi6396 3 года назад

not sure what you're seeing? ... this is U87 purchased from Sweetwater sound back in 99.

@portlandundergroundrecordi6396 3 года назад

@@ShadovvV yeah, don't have an explanation for that one Shadow? You could do some research and get back to me maybe? Got this mic new from Sweetwater in Ft Wayne Indiana back in 1999. Nothing has been changed, swapped out or modded. It's a mystery? Possible thought is they are roughly the same size, therefor the circuit board could be used in either? Maybe they were saving some $ ...

@ShadovvV 3 года назад

@@portlandundergroundrecordi6396 - Well, my guess is either the board was swapped by someone or that's how they manufacture them. I suppose it could also be a mistake. If it's not, then maybe someone did the ol' switcheroo on ya ?

Hey if you need a capsule repair hit me up! I re-diaphragm capsules and build capsules in house not import.

@GrandmasterofWin 2 года назад

This is where I'm at, Tecno. I got ahold of a broken AKG c3000b. One of the capsule lead wires was broken off and the capsule was very dirty. I watched tons of videos and ended up soldering the cable back and following one of the most pro cleaning videos ( the person in white gloves that said DO NOT use any kind of solvent and NO pressure). I used distilled water and bought a paint brush and only used qtips to soak water from the lower tilted side. Never touching the gold and even inspected for any stray cotton fibers. All this to say I'm babying one of the black sheep of vintage mics, one all the gearsluts say is as good as a doorstop, highest price is around $275, and this dude is going in blind on a $3,000 Neumann u87, one of the most cherished mics. Anyway, I know op knows he goofed but damn I don't even have the opportunity to look at one of these things let alone destroy one.

@gregm.857 4 года назад

So what is the conclusion here? Don't do this ... but don't be afraid to try shit? In other words no conclusion. If you want to convince us of something, let us hear the mic before and after you screwed with it. And by the way the awful screaming and noise at the beginning of the video adds nothing.

@portlandundergroundrecordi6396 4 года назад

You're right Greg, I should've done several things better here. Thanks for your comment.
