Hey, i recently came across this Transformer most likely pulled put of an Amplifier but im not sure of current.
It has several secondary windings but no mention of Amps.
Hopefully someone can help me here.
Thanks

The 31-0-31 winding is likely the main high current one (for an amp output stage) and the others for lower powered stuff such as preamp and maybe logic control and a fluorescent display.
Weight it and compare it to lets says a 25-0-25 toroid to get an idea of what the VA rating of the 31v windings might be. I don't think we can be any more precise than that tbh. Also look at the wire thickness of the secondaries. The high current winding (and I'm assuming its the 31v ones) will be the thickest.

And also as its dual supply. Would it be 31v x 5a = 155w or 31 +31 = 62 x 5a = 310w.. how do u calculate the power
I think: (suppose 180 W) P=U*I, so
P/U=I, 180/31=5,81. Using both 31 V taps results in half the current.
But better ask the experts 🙂

From size relative to your hands that looks like a 180VA transformer. So 31-0-31 is a center tapped winding. IF only that would take all the power then you would have 180 VA / 62 V = 2.9 A. But that is only IF the section of the wire for the 31-0-31 winding is able to take that current. Because the others windings will also be dimensioned to take some power. I would not go further than 2.5A for those 31-0-31 and then only if that are the wires with the largest section.
