  Hey guys - I'm having an issue getting -15v at J8-5 before connecting to the main board.
  
  I've gone through the schematics and it seems like everything after D110 shows 0v. (C91, C49, REG2, D96, C93, C141, D94)
  
  I went over each solder point to make sure everything had a good connection, checked diode and capacitor polarity. Could it be the regulator itself?

  Solution: You're likely as dumb as I am and have a 15VDC wallwart instead of 15VAC

Hahaha wow I'm an idiot, thanks Data Jam

Edit: Got lucky and had a spare Presonus 1A 16vac wall wart on hand. Getting -15v as expected now, thanks!
