[QUOTE="JimGore, post: 57252, member: 3"] The lead time of 5 to 6 weeks is a bit long unfortunately. Strange that they operate in that way. I promised you a pic of a steel laminate coil, and here it is. This is the one I did my testing on to determine how much copper, etc is needed. The coil in the photo is 10.4mH, using 18AWG copper, and has a DCR of 0.67ohm I think I could get up to about 12 or 13mH out of a core that same size with the 18 AWG wire. Less with thicker copper, and more with thinner. Regards, Ian. [/QUOTE]
