? To preclude the possibly of a fatally hot chassis, one connects the
amp's chassis to the Neutral from the mains plug.

? which is sorta silly considering that Neutral is going to be
automatically connected to Earth Ground whenever the amp. is plugged into
the mains. However, if a GFI is used, a fourth wire is needed. On
the other hand, GFIs are known to false/trip from RF, so you prob.
wouldn't want to use one for an RF amplifier circuit. .
