I can't get at the cab at present as it's buried in the packing boxes but I used XLR's on mine, but in a different fashion...
As I had a pair of new 75w speakers and a pair of '69 Celestions that still (just about) worked in my 4x12 I wired one XLR for each pair, plus a third with all of them, noting the different ohmage values for each input...
Cut an image from one I had on file...
