Safety / Filtering Capacitors across the Primary on mains powered effects

[Rontone]

I've just done a recap on a tape echo, the last cap is one of those put across the live and neutral on the primary side after the switch, typically a 0.05uF 630V on old units,

I was thinking of just snipping it off, but wonder how bad it could be as reading some threads online it seems they do help with motor units as well as filtering

Its been put in a really awkward place too!

I would replace it with a Class X cap.
