A centertapped transformer might be ether for P-P 47 or 45. Or it can be for Philco 20.
In either case it will work for SE if only ends of the primary are used (and I heard people did exactly that) but at least in theory it is not an adequate thing to do as a P-P xfmr usually has smaller core as it is not afraid of saturation. A SE xfmr usually is a larger one, to deal with DC saturation. So the P-P one might get somewhat saturated which might distort the output and lose the power, plus your primary inductance and all will be screwed up.

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
