Are you sure that pin 2 of both of the 2010s goes to the output transistors? If so, which leg of which output transistor?

You may want to post a request for this in the class D forum (post a link to this thread). Someone there may recognize the components being used and may be able to provide a generic schematic diagram or a link to a thread explaining how this particular circuit operates. I tried to find a schematic. The only source I found wants $20+shipping and will take a week or more to arrive.
