Hey,

Ok, this sounds like it began like as a television transformer. The specs
are right for a one channel power amplifier as well, or even a small stereo
unit.
The 5V winding is to run a rectifier (5AR4, 5U4, 5Y3 etc), the 6.3V is for
the main heater circuit. The 600V is of course the B+. The filament
supplies can run one or two rectifiers, and about two dozen small signal
tubes...
Did you notice another tap anywhere that seems to be making about 70-90V or
so? This would be for a fixed-bias supply, and would give the part away as
an audio supply.
In short, nice transformer.
