Warm WA87 r2 Transformer Swap

Hi all, new to the forum. I have a Warm WA87 r2 that I'm considering swapping the transformer in. ZenPro Audio sells a TAB Funkenwerk AMI T13 Transformer as a direct replacement. Any guides or advice on the process? I'm not new to soldering or repairing electronics, but I don't want to screw it up. Has anyone here done this swap and feel like sharing their opinion on it?
