?  According to your statement, you are also driving the side if the 
heater that is Not connected to the cathode.

>>  Hello List Members,
>>  First I would like to thank everyone for helping me. Its alot easier for
>>me to explain what I propose to do and have someone correct my mistakes.
>>Here is what I propose to do. Tube YC156. I plan on using a filament
>>choke(without centertap xformer). On the transformer side of the choke I
>>will bypass each side to grnd. On the filament side of the choke I will
>>place a cap across the choke. On the side of the filament thats tied to
>>the cathode is where my drive power will enter thru a coupling cap. The
>>bias choke will attach at the same point. Someone please correct any
>>mistakes that I have made. I have never worked with a tube where one side
>>of the filament was tied to the cathode internally. Sorry about the long
>>post.
>>  Regards to All Jeff KD4LYH
