could you please describe what you did exactly? you´ve soldered one wire to to point above 1 of C11 and R from R34, that wire goes to one side of the 100k VR (base contact?) and the other side goes to that big joint on the other side of pcb... but what is that third wire (yellow) for coming from the VR? or is it just the insulation for the red wire?

kind regards
