Wasn't the transformer originally only supplying 6.3v for the valve heaters.
It is likely to be a smaller transformer (mounting holes) than one which can supply the HT and LT voltages on an isolated winding from the mains.
In other words is the replacement transformer you have able to supply the additional power for the HT as well as the LT without over heating.
