looking for info on nad 1600

hi,
anyone out there happen to have a service manual for the nad 1600 receiver? mine needs a new power transformer but nad isn't selling them any more. i'm hoping to do with something else but i need to know the ac voltage output on that power transformer. nad is charging a bundle (and they'd take four weeks to send it) for the service manual so i thought i'd ask if anyone out there happens to know this information.

thanks for any help you can offer.
