Like the Title says. I blew my Xenon 1200.1 and was in the process of replacing all the FETs and also noticed that the power supply coil took some sort of a hit and looks as though it shorted. I am trying to find a replacement but without knowing any specs on this it seems rather difficult if not impossible.
I just went through this with an MS2125. It does look like yours shorted. The easiest way to fix it is to get one from a donor amp and solder it in. Otherwise you can rewind yours but it is a lot of work and very time consuming. Kind of fun though if you are up for a challenge.
