Did I read somewhere that it's inadvisable to use metal bodied jacks on
the amplifier module outputs as the left and right grounds are at
differing potentials?

Or did I imagine that?

Beware of topside solder (double sided board) of drain of Q7109 , crosslink
to Q7103 , both powerFET. Have to remove large C2124 rather than removing
the 30uH to get to that solder point
R3114 , not labelled on overlay of the 300 is 1K , not 470R as the 500
