   To Jimmy.   
   I had a look at the MC3500 schematic. What a beast. It has 8 x 6LQ6 output   
   tubes and complex input driver stages.    
   But the schema say there's a switch to select any load from 1 to 64 ohms.   
      
   So perhaps there's no winding strappings to solder.   
      
   6LQ6 is a TV line output pentode, and what I call a KWEER TUBE. Pda is 30W   
   though. AFAIK, the 6LQ6 is no longer made and was noval based tube, like 7868   
   and a few others, so changing it all to suit 6L6GC or EL34, KT66, KT88 etc,   
   etc, is a huge royal PIA,    
   and then that's ruining American Heritage.
