Is there a prefered method of instalation with regard to lead polarity when used as coupling caps in a pair of Billie amps?
Thanks
Tom

Usually the caps of such quality are marked with respect to the outer foil. There are some methods to find the outer foil and here you can read it how to check orientation: http://www.diyaudio.com/forums/showt...813#post121813 and further, check the comments by jcarr.

I always pay attention to caps orientation when coupling and IME they usually sound best when outer foil is directed to the output. Both polarities will sound substantially different.

Thanks Peter. These dont seem to be marked in any obvious way.

I checked them and installed them last night. So far so good.

Hi,

I've jsut received them and have the same question about the orientation. Since they do allthe caps in using same procedure, I would kindly ask you to tell me the result of your research: orientation of mundorf solver/oil caps.

Thanks,
Matej

This type of cap actually consists of 2 caps in series, same as ERO KP1832, Arcotronics KP 1.72, and probably some other caps used for "pulse applications". As such it should be absolutely symmetrical, i.e. with two outer foils and an "inner foil" that bridges the two.
