Yamaha yg15 schematic needed

I acquired a Yamaha yg15 amp. The power transformer is toast. I'm looking for a schematic for it. I've been all over the internet without any luck. What I'm mainly looking for is the output voltage on the rectifier circuit. Thinking about battery operated.

Google "MA104 mod", you'll be pleasantly surprised if you try it. I snatch up every First Act MA104 I can get my hands on now, do the mod and shove the guts into Acid Cigar boxes

The MA-104 is the one I got. I just changed that input cap to a 2-way switch with the original .047 on one side and a .1 on the other side. The speaker was a large Subwoofer from a TV Surround Sound System. With the Gain turned down and the tone at 50%, you can get great acoustic guitar amp sound with your piezo CBG or plug in a Bass. Just dial up a little Gain for some fuzz effect.
