Thank you for the help.
i busted a part of the circuit that goes to the in out conector. i tried soldering many times but every single time i soldered the conector it had bad contact. would connect the cable to my mixing board and sometimes it would work wth no noise, then if i moved the synth around it becomes noise, so had to touch the conector, move around so fnd a sweet spot with normal sound and not noisy.
So by the pictures i need to do a bridge so i conect the conector to its proper transistor or where ever it leads to.
Can someone help me??
Thank you so much… Am a newby, its my first soldering project.
