Status: Class AB
Output power: 100W  +100W  (8Ω)        < V = ± 45v>
Operating voltage: DC+ - 20V ----- + - 45V
Distortion: THD is 0.002% into 1 kilohertz and full power
                 THD is 0.005% into 10 kilohertz and full power

PCB Size: FR4 138X50X1.6MM      


Debugging instructions：  test any one of the White cement resistance voltage as V1.

( usually the V1 adjust at about  15-22mv will be good)
