[sdiy] Any tips for "restoring" mini-korg (or any synth from the70s)?

If you manage to tear up the traces from a MiniKorg, you should probably
take your boxing gloves off.
They have single-sided PCBs, with no thru-hole plating, and a minimum trace
width of something like 40mil.
They also have a silk-screen that gives you the component values rather than
the designations - which makes life slightly harder if you want to follow
the circuit from the schematic, but makes repair easy.
These are some of the easiest boards to work on you could possibly find.
Having said, that, the only thing I would do pro-actively is to replace the
ancient electrolytic caps.
Anything else, IIABDFI.
