Electronic circuit for Hi-fi class G

They’re perfectly visible to me.

Here is the LTSpice file for the soft clipper, it works in two modes:
1) +125 Volt maximum voltage output
2) 15 Volts below the power rail track

I am also looking at an off-the-shelf PFC rectifier followed by the LT3751 capacitor charger flyback PSU. Four Flyback PSU's for the rails, will try to make the amp 4 channels so a 20KW surge PSU from energy stored in +390V capacitors that have high working ripple voltage.

I was also looking at the IXYS inrush current limiter, I would need to change the design so the capacitor only switches in if the AC rectified voltage is in a calculated window because some generators frequency can vary.

I need to try to phase synchronise the LT3751's

Any PSU experts?

Here is the Keep it simple stupid soft clipper and anti-saturation circuit.

Opto isolators can ring creating ultrasonics.
