Copper Foil Inductors.
« on: 29 Jul 2020, 04:15 pm »
I’m upgrading a x-over and I need a 3.mh copper foil inductor and all I can find are either 2.7mh or 3.3mh. Anyone know where I can get a good 3.mh copper foil inductor.

Would it work to use two inductors of a smaller size together to get to 3.mh.

HiFiCollective in the UK has Mundorf Foils at 3.0 mH

as does Earse in the US

however, I think both are special order and have some lead time.

You  can also buy the 3.3 and  simply  unwind it until your  reach  the  desired  3.0 so long as you  or  a buddy  has  a device capable of measuring  mH

Jay, some one did that for me when I upgraded my Super7 x-over. It was so long ago I forgot who it was.

Thanks Argoncat just order the Mundorf, Parts Connection had them in stock.
