Korg Mono/Poly

Hello,

TL072 ist _the_ standard chip. All your music gear is using those, as 
TL071/72/74 (1, 2 or four OpAmps). There is nothing special about them. 
They cost only some cent (Euro and Dollar).

You should replace only the IC10 (the one for VCO4). Please be careful 
when unsoldering! Don't rip the traces of the pcb.
