Danny, or anyone else,

Somewhere, and I'm pretty sure it was on your site. In a thread talking about crossovers, someone had a link to how inductors in close proximity to one and other and how there value changed.....does anyone have that link?

I've looked and looked, but to no avail, I can't find it

Aside from the math, The thing to do is make certain the inductors that are close to each other are at right angles. So you could have up to three inductors near each other, but if they are situated so they are each turned in a different plane, the fields interact far less.
And the fields drop off square of the distance, (if I remember right) so an extra inch betweeen is a LOT.

YES  Thank you so much Carlos!!!

Thanks Elizabeth as well!!

Carlos, was it in the GR Research forum....if so do you remember which thread?

I hope I'm not pushing it to far, Thanks again Carlos,

It's pretty simple fellas. Draw a line through the center core of the two inductors. They should never cross. You'll see that the ones where he labeled them as 'good', they never cross. Of course distance helps too, but you only have so much space inside a speaker enclosure.

The same rules apply with the orientation of transformers/chokes on a tube amp chassis. Orient the cores perpendicular such that a line drawn through the center of each core never crosses the other one.

best,

Anand.

I posted that link about coils around a year ago in this GR Research thread http://www.audiocircle.com/index.php?topic=74885.msg703882#msg703882
I don't recall how I came across it.
