What does “No RIFA known” mean?
It means the database does not currently document a RIFA capacitor in that model or revision. It does not mean the machine is electrically safe.

Found a RIFA? Report the exact model, PSU revision, capacitor marking and where it was installed. Photos are especially useful for confirming variants.
This is a component-identification database, not an electrical-safety certification. Vintage mains-powered equipment may contain dangerous voltages and other failed components even when no RIFA capacitor is known.

This is a component-identification database, not an electrical-safety certification. Vintage mains-powered equipment may contain dangerous voltages and other failed components even when no RIFA capacitor is known. If you are not experienced working on mains-powered electronics, do not open or probe the power supply yourself—seek help from someone who is.
