I also believe the output transformer needs to be replaced as resistance readings across the plates of the output tubes and centre tap of transformer differs by about 50%. I don’t think this would affect the heater circuit?

If the output transformer reads like you say, yes it's bad.  And if the amp hasn't been properly rebuilt, you will burn up a new one in no time.  That's why you don't even plug in an amp of that age until after it's been rebuilt.

I think you are confused about the heater circuit since it "normally" draws more current than the power transformer.  How are you testing current?
