Rutton,
Yes, the 15V AC will be rectified into about 19V DC then voltage regulated (LM7815) down to 15V DC for use with Allen Write's "Super Regulator" circuit. It is needed to power the onboard Op-Amp/Voltage reference. There is a Super Reg kit offered that can be purchased complete or PCB only. I plan on using two Super Reg boards, one each for +225V DC, and -225V DC supplies. I still need to order the Super Reg PCBs, but plan on doing that this week.
