Vintage Synth Repair

Hi everybody,

I'm trying to repair a Roland Jupiter 4.

I can't adjust the VCo width properly on one of the voice module.

The width adjustment potentiometer is at the maximum but the octaves are not in tune on this voice.

Anybody has an idea what could be the cullprit?

Thank you!

Regards,

Nicolas
