I plan to use this transformer to make a power amplifier. Does anyone know this transformer?

I disassembled it from a second-hand amplifier. It's very heavy. I think the quality should be very good.
the brand is NRE, Who knows this brand ？

A quick search revealed NRE to be a "world-class brand transformer manufacturer":

The output taps are printed on the side of the torroid. Study the amplifier schematic for application hints. You can probably use it for a chipamp project.
