T68kv, sis favor can you post the diameter size of the toroid inductor and the wire gauge plus the no.of turns...?

I'll see if I can find similar size's on 2nd hand boards being sold in Raon area, I've been seeing a lot of boards with toroids in it, I can't DIY at the moment I just burned my pcb drill I might as well go parts hunting for the meantime.


Thanks!

Abet,

Out Dia - 1.2"
In Dia - 0.7"
Height - 0.4"

Approx 20-22 turns of 16AWG

Remember, not all core have the same permeability value. I suggest that you also try using ferrite EE with gap 1-2mm gap.
