In the original circuit, a three-diode string was wired in series to R10. Two of these diodes are now replaced by a red LED in order to achieve improved quiescent current stability over a larger temperature range. Thanks to David Edwards of LedeAudio for this suggestion.
I would be very wary of this change to the bias temperature compensation.

Depends on what type of MOSFETs.

That design is good for lateral mosfets only, but never attempt it with hexfets or verticals.
