Shiino Vesta Fire Compressor (with schematic)

I got a Vesta Fire Compressor of eBay that was not working.
Replacing the 6552 dual opamp with a NE5532AP dual opamp fixed it.
DC jack did not have a wire for GND to the PCB, grounding of the DC power was done via the enclosure.
Here are some gutshots (as can't find anything on this compressor on FSB):
