Default Sony CD changer power supply

Definately not Audiophile but I would like to understand and repair this.
I have a power related issue. The transformer appears to have 3 secondaries ( at least 6 leads mounted directly to PCB. There are a series of diodes and capacitors at the transformer secondaries. I am not familiar with this type of power supply. Actually not familliar with quite a few power supplies but this is my first real encounter of this type of power supply.
Please point me in the direction to learn this.

We would need to see the circuit to say for sure but multiple windings are common and used to derive rails of differing voltages and also rails that need to be electrically isolated or floating from other rails.

Model no ?

If you google the model number you should find a service manual.
