Korg MS-20 Restored

This MS-20 had sat in a basement for some 30 years, and was in a grubby state with corrosion on the jack nuts etc. One key was broken, and the power cable was damaged beyond use. I took it completely apart, cleaning everything, lubricating all pots and jacks. The caps were leaking, so a re-cap was performed. The customer obtained a replacement key from Japan, and I fitted that, along with a new power cable.

A benefit, and curse on the MS-20, are all the jack nuts. When you take the patch panel out, there is another set on a plate over the jacks to remove in order to access the circuit board. The benefit is that these nuts can be swapped for the outer ones, the washers flipped over, and then it looks nice and shiny. The MS-20 came in looking sad, and not making a sound, after restoration it looked and played great!
