Lessons Learned

I went to install the back of the amp components. They would normally include:

• 1 - 1/4" Jack for the Speaker Output
• 1 - 1/4" Jack for the Tremolo foot switch
• 1 - Speaker Impedance selector switch (4,8,16 ohm)
• 1 - Supply Voltage Switch (110v, 220v, 230v)
• 1 - Fuse
• 1 - AC Input Jack

I went with upgraded modern Marshall Voltage Selector, and Speaker Impedance switch. These required a slightly larger than 1-1/8" hole to be cut out where the two little holes in the chassis were. I liked these switches becuase of their low profile. The lesson learned is that I should have done this first before anything else, but I didn't have those switches until the front and the board were in place.
