Default Gallien Krueger 700RB blows fuses

I am looking for some help with an amp that is blowing fuses between the transformer and the bridge. Two of the four fuses blow when I turn it on. If anybody has knowledge of this amp or the schematics for it I would really appreciate it. I have electronics back round but haven't done this for quite awhile.
Thanks, Tom

Fried outputs or bridge.

Use your ohm meter and replace the bad parts. Keep moving back a stage until you find no damage, then replace that stage too.

After repair, insert a lightbulb (75W~100W) in series with one side of the AC line before firing it up.
