Hi. Im gonna do a multitap toroidal inductor for a friend that want it for an Altec 9069b HPF clone. Seems to be a LCL Pi filter. They want it toroidal because he saw internal pics and seems to be a toroidal type... He showed me that pics and I saw like two or more toroids and no capacitors, maybe they are "packed"?
What I dont know is what material to put in the core, Can I put there a ferrite one? an Iron powder one? is that critical in an audio filter for line levels? Can someone guide me?
I read somewhere in that forum that I need to do complete n rounds with an inductor to avoid problems with increase in distortion... In a multitap, I need to do that with every tap?
Thanks
Arnau
