Well, I did not check detailed ho amps works but the 'crude' wattage of amps are depend on how high your rails and how high your speaker impedance. Just simple ohm law V=I.R and P=V.I.
Because you don't mention your output impedance we don't know thw wattage, how many pairs mosfet needed and how many amps to feed the gates, basically whole amps

Hi,
simple answer is not really, there are far better ways of approaching
such power levels, e.g. multiple rail class G amplifers.
Though it seems it has +/- 180V rails and is bridged.
IMO there is totally not enough juice to drive
the gate capacitances of the output mosfets.

For so high voltage level must consider the power dissipation = loss power = heat. Then the choice is only lower rails = lower impedance or class G,H and class D,T. Hence simple rails to rails is not a choice.
However for that high power (32kW) must be in speaker array and better feed by multiple amplifier. I wonder that people think to make single amp at very high power = expensive = complicated (class G,H except class D).

Its not a 32kW amp, its a 7.2kW amp. And the heat would be no problem with that scaledup output stage.

the Drains. Clearly this amplifier was never built.
Exactly!
Moreover input polarities are swapped forming a positive DC feedback.
