Mouser has CDE 8 uF 660 VAC. 11 are on order from the manufacturer. https://www.mouser.se/ProductDetail/Cornell-Dubilier-CDE/SFA66T8K475B-F?qs=sGAEpiMZZMu3dWSqd4Tl0A9wIZdhZWWRKQi0fpV8QTUDmNGSFUtTTQ%3D%3D I have replaced several of these capacitors in PDP-8, LA30, PDP-9. /Mattis > Thanks! > > Kyle > > > >
