Repair low cut, pad switches of a Neumann U87
« on: August 02, 2019, 11:12:38 am »

I have seen many U87 microphones with broken pins of the low cut/pad switches.
Is there a good way to repair those switch pins?
I know that Neumann sells the complete switch/capsule mounting assembly, for a pretty high price.
(I don't think $471 is a realistic price to replace a single broken switch pin...)
I found that Soundlock Engineering is selling replacement switch sliders that are 3-D printed.
Any suggestion is highly appreciated!

I buy plastic rods of the correct diameter and color, cut to size, bevel the tip to the exact radius of the original, drill out the broken-off switch section, then insert and glue the new rod into place.

Indistinguishable from the original, when done right.
