Some of the imprints are not legible.
Q7-Q8-Q7R have the following voltages at the pads:
1(gate) 5.318vdc
2(drain) 80.1vdc
3(source) 5.732vdc


Q8A, Q11, Q9
1 (gate) 12.31vdc
2 (drain) 5.726
3 (source) 000.0vdc
The other side of outputs correspond to these and are identical.
 
One of these I/C looks like it may have had a problem. There is a heat spot on it.

The IC in #26 could be defective but the silicone die is generally centered in the package and the IC next to it also appears to have a circular mark.

You post that the voltages on the IC are DC. Does that mean that it's pure DC or are you using a multimeter instead of a scope? Are there any waveforms on the outputs?
