I've just bought a vintage Sew -Tric motor and after connecting to mains I heard a bang. I attach a picture showing the suppressor. I need to replace this as it's reading 18K when it ought to much higher. Original suppressor made by Dubilier, part "SPM 669". Will replace with a brand new suppressor when I identify one. I see that there are no RFC's in this, just 3 capacitors. That metal round bit you see has (I'm assuming) to go to chassis, which it does as it's pressed into the compartment made for it. Also printed on suppressor is "0.025uF + 2x .0025uF". So, I'm looking for something similar.
