   Most of the EL34 made today are impossible run over 650V.   
      
      
   ** That is  100%  BULLSHIT  !!   
      
   The plate supply can be up to 750 volts on any EL34 worthy of the number.   
      
   The screen supply must be not exceed 400 volts at the same time.   
      
   Tens of thousands of guitar amps use them this way -  eg  MusicMan and   
   Dynacord.   
      
   Peak plate voltages can reach +/- 5kV without failures, long as the base and   
   socket hold.   
      
   Smart designers include reverse diode strings on each plate to chassis to   
   limit peak values.   
      
   Pat will give you the details ....
