   807 is the transmitting version of 6L6, so it's no wonder that it looks   
   similar.   
      
   For the power level you're after, you may need real transmitting tubes,   
   e.g. a pair of 3-500Z's. Please understand that the voltages and   
   currents encountered at those power levels will be lethal in careless   
   hands.
