sounds like the offset didn't change magnitude, just polarity; shouldn't be a problem

This is significantly bad; worse, in fact, than your original problem

There's no sense in continuing to troubleshoot ANYTHING until the rail voltage prblem is fixed.
This can be alot of things here. A component in the amp section could be drawing the rail down so far it isn't adjustable. A component in the traic control could be bad, not allowing the triac to fire enough to meet the rail voltage. A component at or after the power supply filters could be dragging down the rail. The rectifiers could not be providing enough current to meet the rail. It could
be alot of things.
It's most likely something you changed or removed. Go back and check your work. Check for shorts to nearby traces. If, after un-doing verything you did, it's still not working, then we'll have to start anew troubleshooting the power supply.
Oh, and never change too many variables without checking the results in stages (hind-sight in this case, but lesson learned).
