MOTU 828 MKII NOISES & CRACKLES: the ULTIMATE REPAIR DIY tutorial

It's well known that a number of MOTU 828 MKII MK2 have defective MIC/GUITAR inputs causing very annoying and unpredictable noises, even with sensitivity TRIM set to minimum.

To proof it just disable completely MIC/GUITAR inputs and see if noises disappear.
The cause is in two potentiometers with defective terminals (not the usual wiper problem of pots).
They are IMPOSSIBLE to find in the market.

In this tutorial I will explain how to build compatible potentiometer, even on the mechanical point of view, and fit the problem spending only about 10 $ !!

Please be aware that all this DIY repair will obviously VOID THE MANUFACTURER's WARRANTY, but I don't think it's an issue for this old product... :)

Enjoy!
