Which two legs of IC10 and 11 are connected together?

From what I can tell from the photos I have...
Q10... are all FQP19N20s
Q11... are all IRF9640s

There are not connected ,ic10a and ic11a are the two transistors to the far right of the circuit. I was just wondering if i could assume that ic11a would be the negative and ic10a would be the positive giving that a10s are n-channel and a11s are p-channel

You shouldn't assume anything.

Did you use a multimeter to confirm that there are no two pins from those ICs that are directly connected?
