   gain of valves is reduced by their unbypassed cathode resistors. Apart   
   from that my explanation of the working of the circuit remains

   Some clowns have since muddied the waters. The Butcher in particular   
   has, as usual, poisoned the thread with nonsense, and misled and   
   discouraged the OP. I find that behaviour simply too disgusting to   
   witness, so I shan't be hanging around here much.   
      
   cheers, Ian
