[HAM] speaker connection on M-100

[Stainless Brown]

I'm in the process of putting my M-100 back together, the previous owner robbed the reverb amp and one of the speakers from it.  I never really looked at the speaker connection before, always assuming that the missing speaker was for the AO-44 output, however I notice that the remaing 12" speaker (in the center) has a set of parallel "jumpers which would conveniently connect to the other (and adjacent)12".
   
  The 8" speaker seams to get one lead from the main power amp and the other comes from the tone generator
   
  Any ideas?  
  Thanks
  Stan
   
  PS, I still have the Leslie x77P power supply and amplifiers if anybody's interested for the price of shipping it.
