   Which Mesa guitar amp has 12 power outpu

   There is supposed to be one of the Mesa guitar amps that uses 12 power   
   output tubes in some sort of push-pull parallel - parallel manner. I'd   
   like to look at the schematic, just to see how it's wired. Most or all   
   guitar amps have online schematics, but there are 50 or more models made   
   by Mesa, so I dont know which model to look at.   
      
   Does anyone know which model this is?   
      
   I'd also be interested in URLs for any other amps that use more than 4   
   power tubes.... I did find a poorly made drawing of a Fender 400, which   
   has 6 tubes. The schematic is hard to view though.   
      
   I've always wondered if there was any limit on the number of tubes that   
   could be paralleled to gain huge power wattage outputs. (Of course I   
   know the size, weight and cost of the output transformer sets limits).   
      
   Thanks
