First, i intentionally make it not easily accessible as it really requires good soldering skill and equipements.
But here is what involves:
1) power amp board: replacing servo board with vented version, changing the MILLS sensing resistor from 0.22ohms to 0,1ohm
2) preamp board: swapping SMD jumper between R801/R802, clipping off two back soldered 12kohm resistors, and swapping out jumpers 2/4 to jumpers 1/3.
As you figure, you need to desolder an SMD device and do some other soldering.
