So this amp is class D and that L-C filter should remove the 200KHz
switching modulation, but is 1.5 pk-pk acceptable, time to visit s.e.d I
think.
Uses Si8244BB soic, at least there is full data on that, PWM input to
that and so presumably driving a pair of powerFETs under the h/s clips ,
not Darlingtons
