unclej Posted August 23, 2006 Report Share Posted August 23, 2006 i just received two 50/50@500v can caps from ce distributors to replace a couple in an amp i've been working on. they're lcr caps but..the ones i'm removing have a red drop of paint on one pole, a yellow one on another and none on the third. on the side of the old cans it states that the plain one is negative. on the two that i just received only one of the poles is marked and it's marked with a black dot. logic tells me that that's negative but i wanted to check and see if anyone knows for sure before i install them and blow this thing up. i called ce distributors and nobody knew for sure. thanks Quote Link to comment Share on other sites More sharing options...

I would also deduce that the black dot indicates the negative pole. Quote Link to comment Share on other sites More sharing options...

Paul Marossy Posted August 24, 2006 Report Share Posted August 24, 2006 thanks...i say we blame it on lovekraft if it blows up. He he. I don't think it will blow up, though. Quote Link to comment Share on other sites More sharing options...
lovekraft Posted August 26, 2006 Report Share Posted August 26, 2006 In general, if only one lead of an electrolytic cap is marked, it's the negative side - there, now if it blows up, you really can blame me! That's one of several reasons I never use those old-school can caps if there's any possible alternative. Why am I not surprised to hear that the guys at CE didn't know either?
