Compare physical inventory to the included bill of materials. Packaging mistakes are rare for Mojo but 

double check us before you start your build.

Tube Sockets - Install so that they all face the same direction (noting pin #1 orientation)

helpful for anyone looking at the transformer model number without having to take the chassis out of the 

amp.

Install Input, Output Jacks, and Switches. 

• 

Fuse Holder - Install fuse at same time so you won’t forget.
