Bernina 707 Sewing Machine?

Hi
My wife has a Bernina 707 sewing machine which is about 38 years old and has been working fine until today. It appears the 4 lead capacitor for the motor has blown. Capacitor is marked as follows:
Aps 16xb +12 250v
2/3.5 mhz 85 deg C
9.70
I would mention that I am an electrician so could easily fit a new one, but having difficulty finding a supplier - which is understandable after all these years. Any suggestions would be most welcome
Regards
DL
