Stupid Capacitor Polarity Question

[punkin]

Hello All,

I'm working on a BSIAB2 and kinda at a cross-roads  . I'm installing the "C9" capacitor as listed in the GGG BSIAB2 schematic. It's a 1uF Metallized Polyester Film cap (Mouser PN-75-MKT1817510065 http://www.mouser.com/Search/ProductDetail.aspx?qs=%252baGcqN07%252b8RJ7aFjZ8uF%2fA%3d%3d ). The GGG parts list called for this type of cap and according to the schematic is calling for a polarity complian installation. I can't seem to determine which side of the cap is positive and which is negative.

Any help?

I thank you one and all
