Mopho X4 Replacement Oscillator Tune Encoder and Output Jack

Hi All! I just picked up a Mopho X4. It nicely complements my P6 desktop!

The Oscillator Frequency/Fine encoder has a broken shaft, and an output jack is cracked.

Before I email to Sequential, please advice for encoder specs, pitfalls, experience, advice, etc.

It would be cheaper for me to re-solder the parts rather then servicing the entire board.

Thank you!
