Marshall MG100hdfx Fuse Blowing!

[mds484]

Just replaced the whole power module ( www.marshallparts.com/products/1778/Power-Module-for-MG100-DFX.htm ) for my amp and im still blowing fuses! The reason I replaced this module is because I let a friend hook up a home made talkbox to it ran through the speaker out and nothing else. I believe the resistance was incorrect and fried the part and blew the fuse. So, what is common that would also need to be replaced or what is blowing my fuses? Here is a link to the schematic for the head. www.ampix.org/albums/userpics/10003/MArshall_MG100DFX.pdf

Thanks in advance, Im new here.

Hello and Welcome!

Unfortunately, I have no idea why you're still experiencing this problem after replacing the power module. But someone with more saavy on amp issues will be along soon.

What's it do when the PA module is unplugged from the rest of the amp? Meaning, does the fuse still blow immediately upon power-up?
