The compander is just mis-biased on the expander outputs and so hitting the rails.
I can't remember the calculation off the top of my head but you should be able to stick a resistor from pin 12 to ground of the NE570 and that'll shift the bias, aim for 4.5V on pins 10 & 11 (or 3V if you prefer to keep it like the build doc, it shouldn't really matter).
Start with 10k.

I know you're super busy but would there be anyway you could post the build doc for the Coral Reef or at least a parts list? Would like to see what I need to collect before you release it.

VFE boards already sold out or cart bug?

We just got a 50W laser at work that seems to be blow through everything (although I haven't tried a black enclosure yet). In fact, I had to dial it back way more than 40% because it was burning back a bit too much.
