I opened my blue stripe Mark III today to take a look around and snap some pics to compare to other gut shots. I found this weird little box that I can't find in any other mark III's. Anyone have an idea what this is? The board around it looks burnt and the solder job isn't the cleanest so assuming it's not stock. To anyone who knows these amps, does everything else look stock to you? blue stripe, simulclass, reverb, GEQ.
Thanks for any help
