   Hi Patrick,   
   don't laugh - I deleted some lines about those old ampegs and the   
   Baxandall... Did I really delete them? =:o   
      
   the components I'd consider to measure and clone ain't the pots, but the   
   caps, the slope resistor and the cathode caps (them throughout the whole   
   amp). It's the whole system - not just the tone stack. Differnces might   
   be subtle. You are dealing with - humans - worse: artisans   
      
   For me the speakers themselves don't need to be "old". IMHO the   
   particular OEM-Emi in the DRRI is simply a piece of shit. It does not do   
   any justice to the capabiliies of the amp.   
   New speakers ain't generally bad. You've got a hunch of choices   
   nowadays. IMHO there are some Speakers to consider with a DR:   
   EMI RedFang,   
   Celestion Alnico Blue,   
   Jensen Electric Lightning,   
   the WGS Blackhawk,   
   Celestion G12-65;   
   EV-12L   
   et al   
      
   It's simply a matter of taste.... Myself, still opinionated, that   
   "better" is not always necessarily "BETTER"..... But I hav e to confess:   
   I'm a convinced player of an old 5E3 Deluxe Repro with an 12" Alnico   
   Blue RI - far away from technically perfect, but a real fun machine ;-)   
      
   regards
