Polarity on the Infini cap?


Just got a pair of the Infini caps to replace the Kimbers in my AE-3 pre. The Kimbers have different color leads for polarity but the Infini's don't. Any idea as to how I should install them? Thanks in advance.

If you look at the label on the capacitor and read it left to right, then it is suggested that the signal come in on the left and leave on the right(which sounds nuts since this is an alternating AC voltage) but it is how the cap is internally made. Other than that, there is no "Real" polarity on the small signal caps. Hovland and Kimber look very similiar. The caps I have use had a red and green lead with green being the incoming and red being the outgoing according to the manufacturer. However, they also said that you should try them both directions. You can go to the Infinicap web sight (TRT) for more information or call Michael Percy @ Percy Audio. Hope this helps.
Herman, I buy what your selling and it might make a difference in absolute terms(maybe.) However, as I stated earlier, manufactures say try them both ways. The Infinicaps are not marked for polarity and neither are many other caps. When they are of very small uF value, they will work either way. It is a matter of how the cap is manufactured in regard to construction of the dielectric. Some caps like this, it really doesn't matter which way they go. Kimber and Hovland use green and red leads for orientation, not polarity. Generally, you go with best sound. If it was a big issue, manufacturers would label the caps as such. Big power supply caps are another matter. That is why the have a definite + or - designation.
