   Well, you say bipassed, I say shorted. Or maybe I should look at the   
   circuit. But I don't see how it can be simply bipassed without the end   
   of the winding being effectivly connected together at AC.   
      
   I suppose if you had two sets of windings, the first in the anode as   
   normal, the second in the cathode out of phase with the first, and a CCS   
   also in series with the winding in the cathode circuit. Then both the   
   CCS and the winding bipassed with a cap it would do it.
