Well here is what I have tested, maybe I am looking at this wrong.  With the 80 and 45 tubes out, the voltage on the filaments is 1.4 and the amps are around 8.  With all the tubes out the voltage is 2.6 and the amps are 0.  I checked each tube socket to ground and all along the filament wires for a short.  The ohms on the filament section is .1.  It does take about and hour for the the transformer to get hot to the touch.  

I have not pulled the transformer and opened it up, but I will.
