The nearest to this is the Edwin topology, but no real advantage.

The LV OP runs till it is close to it's rails then the TA2031 switches the audio signal to the higher HV OP stage.

The switching is such that they never conduct simultaneously.

It is also not that the LV OP's handle a clipped signal and the HV provides the additional "crest" of the sinewave, but that lets just says that given a single cycle of a sinewave, and assume it represents a bell shaped curve, 2 standard deviations are handled by the HV OP and the rest by the LV OP stage.

The obvious advantage is that no set of outputs sees greater than +/-50 vdc or so across their CE's so dissipation is very low.

Default does this sound right?

so under HV the LV will be reverse bias, eliminating V drop over output devices (i noted theese large diodes)

Default Kenwood Basic M2A Schematic

I have the Kenwood Basic M2A Service manual that I have scanned at 600dpi and burned on CD. I list this on eBay from time to time. If anyone is interested, I can relist it.
