The H-Bridges for the left and right leg are identical. The main driving transistors for the H-Bridges are A928A (PNP) and C2328A (PNP) the datasheets for which are available here and here. Each H-Bridge appears to consist of several resistors and 8 transistors. At some point I will make a schematic for them.
