Thanks for sharing.. with most parts already in hand I could actually build that! Safe to assume it wants a low Z input with a fair amount of volts? (<10?)
it depends
I'm feeding my F4 Koan with few volts , in my workshop
mostly enough not just for daily FM enjoyment , also for occasional digital bursts

tnx
this is proof of a pudding ....... not exactly proof in a pudding 🙂
si , it is doable , Iq around 1A6 as predicted per spice
it'll need sort of speaker delay , just because there is nasty voltage peak in startup sim
this is far from optimised** , THD is 0.1% at 1W , though THD spectra is schweeeeeeeeeet
**demanding both more time with LTSpice and then real deal - playing with it in vivo
Hi ZM. Interesting circuit. Pls check FET Vgs values; -5.3V for P-MOS and -3.8V for SIT?; reversed?
I'm certainly dumber than LTSpice
though , even if I'm finding it really useful , there are some surprises always , in vivo
however , you can count that that sim is pretty good for start

Hi ZM, if possible, could you kindly share your 4n35 model? I am searching a model that fits better to M2 operating condition. Thanks.
Mr. MR , have you SJDP model , too ?
and , just now , I'm having an idea of trying it with cascoded LU ...... it would allow full blast (meaning regular FW range of PSU voltage ) version of amp
will sim tonight ....... and just dream when I'll have time to try it in vivo
another proof that pudding exists 
real pudding is on da Bench
startup behavior pretty benign , no need for speaker delay
cascode voltage fine-level trimpot advisable , you can put pot there and call it Zen Amount Pot ........ something as in PapaSit-1 🙂

R2,R3 ..... keep their ratio
though , I wouldn't recommend changing anything in circuit without prior confirmation in Spice
except if you know what you're doing ....... in which case you wouldn't ask for those resistors
