Hello, I want to replace Multi-Trak’s Control knob, some buttons, and battery.

Would replacing Trim potentiometer, Pushbutton tact switch, and battery be just a simple soldering job, or it would be more complicated to replace them than just soldering?

I’d also like to know which Trim potentiometer is used for Multi-trak’s Control knob. Is it 10K or 100K one?

Finally, please let me know if there’s any replacing parts available for pitch wheel portion.

Any help would be appreciated, Thank you!
