Title: Broken piece in AT-U853 microphone
Post by: robgronotte on July 06, 2026, 11:55:20 PM
I recently got a slightly used set of Sound Professionals SP-CMC-4U microphones. They're made from the Audio Technica U853 bases and capsules (which I believe have the same internals as the older AT853).

I tried them out once and they worked fine. But for the next use I was trying to figure out the clips I got with them, which I had a lot of difficulty in positioning in useful way.

I could barely even move the clips with the capsules on, so I removed the capsules to fiddle with the clips a bit. At some point I noticed there was a little gold tab sticking out from one of the bases. I tried to bend it back the other direction to match how and it immediately snapped off.

I'm hoping this will be an easy repair if I get the correct piece, but I don't know what it is called. It's the piece of the base that actually makes contact with the interior of the capsule. I don't know why such an important piece would be so fragile, especially in a set with changeable capsules.

I would appreciate if anyone could tell me an easy place I could get a replacement piece, or even what it's called, and any advice on the repair.  I may contact Sound Professionals about it, but thought I would ask for insight here first.

Attached is a photo of the intact base, with the tab sticking up just a bit.  It was tough to get a photo which showed this piece very well, but hopefully some will recognize it..
