Peavey Bandit 65 transformer

[mr.death]

Hi, Recently I was given an old peavey bandit 65 amp with issues. I replaced the old electrolytics and in the process some solder dripped across the board bridging some traces. I turned the amp on not knowing and fried the transformer as a result. I need a replacement transformer but am having a hard time finding one thats not bloody expensive. What criteria needs to be met when looking for a new transformer? Can I buy not peavey branded, generic? The part number for the fried part is 70518713.
Thanks
