Building coils--Eric or

A

Anonymous

Guest
It would be nice to know how to build a coil for a P.I. I understyand they are fairly simple single writings, shielded, and apparently a damping resistor. The guage of wire, resistor(how connected) and isloation facts. While I assume they would work on any P.I., lets just take Eric's designs. Coil sizes-- 8", 11" and 14" mono. Thanks!!!

Yes there are several designs available on the net. Try the following sites for some information and designs. I can't say how good they are since I have not built any of them myself, but some of the folks in this forum have.
