Actually transformer form 20, 2766, could be used as an output transformer for 70, as it is a universal PP/SE transformer, in the latter case the centertap is not used, when it is used for 1x47 output. So the 20 speaker is fully good for 70 except you have to re-wire the way the transformer is connected
