Pioneer sa-8100 power transformer, need the specifications

hi everybody, i have bougth a pioneer sa-8100 solid state amplifier several year ago fron the recyclers in a city of peru, the isue is that they ripped out the power transforfer to sell the copper (what an aberration) before i can rescue it, any way, im goin to fix it, Taking advantage of my knowledge of electronics and my love for high-quality vintage audio equipment I need the specifications of the power transformer, amperage, output voltages and, if possible, the core measurements to be able to recreate one as similar as possible. if some body has that information, i would be very gratefull. thanks!!!
