High Voltage Boosted Rail to Rail Output Composite Op Amp

Found this circuit the other day and was reminded of our common emitter output discussions for a +30 dBu output. https://proaudiodesignforum.com/forum/p ... t=50#p6664

The above approach is a little different from our 2013 discussion in that it has thermal feedback and that the output stage is common emitter formed by a current mirror.
