Q4 collector to GND?
Would it change performance if this collector were to -V?

Hi, I live in indonesia.
With that choke, half DC voltage will dissipated to hot 4r7 resistor. You could use boost converter to supply V+ , instead of dissipate it with 4r7 resistor.

Hi my friend,
thank you for wiewing, you may notice 4r7 is actually 15w6ohm8. I will post demo kit now.

supply V+ 24 and V-24.

Hi my friend
you can see power supply is +24 and -24, Q4 collector to GND this ok.
