Mesa Mark III, What is this...?

[jkkkjkhk]

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

Well, it's a resistor, and it's hooked up in the diode bridge for the low voltage supply if I'm not mistaken. Looks off to me...

Have you tried asking on the Boogie Board? Super knowledgeable guys over there when it comes to Mesa Mark gut shots.

Looks like the voltage supply for the LDR switching took a crap at some point and had to be rebuilt.

Thanks, I haven't posted in on the boogie board yet but I will, also after checking around last night I realized for the last 2 years I thought this was a blue stripe, turns out it's actually a green stripe.

Looks like a hack job repair. Might be worth sending it to boogie to have it spruced up...
