Possibly but not necessarily. Did you remove all the other tubes also? There are lot of them and all the filaments combined will put a significant load on the transformer. 

What wattage bulb are you using? The power transformer is pretty large and can draw appreciable line current.



Do you have a Variac where you can bring the voltage up slowly and see when the AC line current starts to increase?
