Hi, I have a replacement transformer I'm going to install in my Peavey Bandit 65. Its not a direct replacement so the mounting holes are different. Question is does the transformer have to mounted a certain way? Does it latter which way is up? Thanks

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
