Nice. Was there a sensor on the transformer they removed? Also, what is the "new" redish wire running from the rear right pot (facing the rear of the amp for position) running to the pcb near the singular orange cap in the front? Didn't see it in the "before" shot.

That's not a sensor - its a bias adjustment mod someone in the distant past installed. I had Mesa remove it.

Don't know whats up with that added wire. Good eye dude.
