I just dropped a Neumann 67 from the shockmount

...all the way onto the mic stand base.

Now it rattles like a baby's toy.

I've never opened one up before. Is there a tube in there?
Please tell me I'm hearing a broken tube rattle around in there,
and not electronic debris.

Yes there is a tube in there - and while it's not as pricey as some, it is probably in the $150-200 range.
Hopefully that's all that is broken.

If you unscrew the cap at the connector end, the tube slides off the bottom of the mic exposing the electronics including the tube.
There are then two metal 'rails' running down the length of the mic. Inside the rails are two spring clips which you can squeeze in gently to unlatch the capsule housing which can then be pulled from the top of the preamp body.
Once the head is detached, there are 3 brass flat-head screws that can be removed to release the screen - though it is a little tricky to get that off because of the tabs on the pad/pattern/cut switches, but it will come off.
That last one will expose the capsule to let you see if there is any significant damage there like a broken mount or a damaged diaphragm.

Is this your mic, or a rental, or a borrowed mic?

If you're the one responsible for repair, I'd recommend talking to Korby Audio. I sent mine out to Tracy just for new tubes, a check up and his modifications, but he can repair as well.

it's a studio mic where i work, so it's not mine.

it landed pretty hard on it's side, so i'm hoping there's no capsule damage.
i started to open it up, as glass from the tube sprinkled out.
then i realized, the huge dent in the side was going to prevent me from removeing the shell. so i dunno what to do about that.

i already talked to the studio owner. he knows someone at neumann, so we'll see what happens. hopefully it won't eat up 4 months pay.

just wondering the outcome...did you get fired (lord knows back in the day my ass would have been out the door before it hit the ground...)?

It's good to know someone at Neumann, but I was under the impression that they had stopped accepting vintage mics into their service department because they were getting too clogged with old gear and wanted to encourage people to purchase their new products which they naturally feel are superior.
But Gefell takes in vintage Neumann products for repair if the guy feels better with a manufacturer working on it.

well, you dropped a 6000 dollar mic, didn't know it was tube mic (when it's one of the most famous mics made), and aren't fired yet? i want that job.

Yeah, what the hell? I thought I was the only one on here with a government job.

Holy bejesus. You better send it to me so I can retire it. No point in trying to save it now...its dead to you.

Well, as you may have figured out, I'm not that big of a gearhead. I dunno much about electronics per se. So, I assumed there was a tube in there, but never opened one up to check it out and be sure. I'm more concerned with how things sound. Although I admit I should know more of the tech stuff.

And no I'm not fired. I called the studio owner immediately to let him know what happened, and to let him know I'd be doing whatever it took to fix or replace it. He's pretty understanding... accidents happen. It's not like we're a high traffic NYC studio. We're pretty "Ma+Pa" around here, plus I'm a freelancer.

But, I may be working a few months for free in the long run. But I've got a good track record here. Plus, I know the mic has been repaired once before.

knowing that a U67 is a tube mic has nothing to do with being a gear head. it has to do with being an engineer.

Don't be a jerk! Something really bad happened to him!

woah is this gearslutz?

Thanks Professor for the detailed instructions on how to take the mic apart. That will be helpful for others in the future.
