   Good to hear that 6L6GCs work well at 360v in your amps. Parallelled cathode   
   resistors must result in less heat, nice solution.   
      
   ** Same amount of heat  -  just more spread around ..   
      
      
   My pair must be late production, serials in the 70xxx range,   
      
      
   ** My one has s/n 8734   
      
   because they have no voltage selector beside the fuse and no Bulgin power   
   connector. Instead there was just a hole for what I think had been an early   
   IEC C10 plug. So I could fit modern grounded 3 prong IEC there without any   
   drilling. It seems that Quad made some different chassis configurations for   
   different markets?   
      
   ** German products once used an odd IEC like connector with two pins and   
   ground via the casing.   
      
   Same panel cut out I think, see them on old "Dynacord" amps and " Echolette"   
   tape units from the 1960s.   
      
      
   Im in two minds about the Jones connector.   
      
   ** Schizophrenia is hard to cure....   
      
      
   On one hand it looks retro funky.   
      
      
   ** Huh ?   Looks appalling to me.   
      
      
   The only giveaway that the amps have been modified is that I placed AC   
   switches where the fuse holders were. But they are old British chromed   
   switches and look contemporary. The fuses are now inside the enclosures.   
      
   ** You have just given me an idea....
