Shouldn´t be too different to this one, only using smaller transistors, say TO220 outputs instead of TO3.
Designers tend to follow favorite "recipes" in various products and in any case this amp is almost as simple as can be.
NOTES:
* Q5 is correctly labelled as PNP but is drawn upside down (invert Collector and Emitter)
* maybe yours does not have short protection, so mentally remove Q8/9 - D7/8/9/10 - R16/17/18/19 - C6/7/8/9/10 or print schematic and cross them out.
* wouldn´t be surprised at them making a "one size fits all" PCB where they can build anything between 30W and 100W, so your PCB might have unused holes.
Post a picture.
Torque in general used discrete amps (such as this one), not too fond of chipamps.
