Default Re: Toroidal choke failure

I would suggest caution in rewinding or making a replacement unless you have the specs of the original.

Especially using a lighter gauge wire, there can be some very high peak currents in a class D amps output stage.

Class D amps can be very fussy as to that choke.
You need to know inductance, resistance and type of core.

If it's wrong, the output transistor/s (or FET, MOSFET etc) could be toast.
