In checking the power for the tube filaments plus assuming a plate 
voltage of 300 @ 100 ma. and throw in a couple of dial lights and a few 
losses then the 57 watts is just about right.  I have quite a few spare 
transformers so if you figure out the voltages required I might be able 
to supply one.  Not a direct fit but you might be able to shoehorn it in.
