The emi from the conductors and wires will be more significant than from inductor

Emi from the inductor wires..yes...i though alot how to shield the inductor and made several experiments but without good results....the ones you posted i never tried..maybe in the next version..

Emi from the speaker wires can be reduced also by using an additional low pass filter after the amplifier.

PQ are hard to get ,
From the RM14 you can easily make a 30uH 40Amp inductor

the LM311 + phase inverter parts in the first post of this thread, are still correct?
Or, which is the latest schematic update for that section?
