U89 maintenance

Hi fellow slutz

I own a 15-20 years old U89 which gets used on daily basis and I was wondering what kind of maintenance if any it needs?

Thanks!

Well unless there is an issue like damp on the capsule causing the mic to drop out for a little while, that's usually just a matter of getting the worst of the congealed snot off the capsule, but apart from that or other noise type unusual activity, you just ride them Neumann's hard and put away wet.:-)

Mine was made in 1979. #262 serial. Still in beautiful shape. I am attaching an old post of mine containing literature (PDF) from Neumann about how the capsule does not really need to be cleaned.

"Microphone capsules:
The microphone capsules of U 89 i, TLM 170 i and the KM . . . miniature microphones
are constructed in a way that the total surface is connected to
0 Volt. For this reason these microphones are extremely insensitive against
dirt and atmospheric influences and should not be cleaned"

It also contains info on cleaning other Neumann capsules but

I DO NOT RECOMMEND IT!!!

Look for my post #17 for the PDF file here:

Neumann U87Ai strange behavior: faulty or normal?

Pull off the grill and inspect the capsule for crap- don't touch it, just look. I would assume it will be fine- but its WORTH LOOKING.

Breath test- google it.

Ears- does it sound good?

Other than that call it a day!
