In an effort to revitalise my Mesa Fifty Fifty it's going to receive a new set of filter caps, bias-pot and OTs with more iron to them. As seen in the photo below the bundles of wires from each OT are cable-tied separately. Then for the 8 ohm outs the orange wires cross over to the yellow wire of the opposite OT. Any particular reason Mesa would do this, you think? Those 2 x 4 ohm outs below (mostly obscured by the yellow and orange) are a single green without any interference from the opposite transformer.
