Just to clarify things, DC and low frequency AC travel through the center of the wire, as frequency goes up the current moves to the surface, typically around 3 MHz and above. For frequencies we work with, usually DC, audio, and digital below 1 MHz, the current travels through the center.

Top of page "Post New Topic" and no I haven't had problems with beans, but I do know there are several manufactures and I'm sure they're not all equal.
