I'm making a MOSFET amplifier and I have these questions:
the gate zobel network is better if it is from gate to drain or from gate to ground?
In case of gate to ground at what ground should i connect it, feedback ground, power ground or loudspeaker ground?
Finally for the output zobel network what ground should I use?

Zobel network must be placed across speaker terminals, neither at gate nor drain of any FET. This is to correct the impedance seen from the amplifier at high frequencies when the speakers makes more and more inductive impedance and "rejects" power back to the amplifier.
