I need help to fix my Plinius M8. Specifically its Toroidal Transformer Power supply. Attached here are the pictures of the unit and the drawing. I was hoping if anyone could give me a data sheet or complete specifications of the power supply which is the Toroidal Transformer of the Plinius M8.

Do you have a multi-meter ?
If you do, you need to establish the secondaries.
It is unusual for a pre-amp transformer to fail.
They do fail if they are poorly specified but it is unusual.

Try and get ohm readings between the twisted pairs, they should be low, why do you suspect the toroid has failed? While you're at it check across the fuses f2 looks blown.
Also I see right after the transformer terminals on pcb there are 1 amp fuses, the look like resistor, check if they're open
i already sent it to a technician. He said that the toroid is already fried. Then i tried to send it to someone who rewinds but they lost the part. That is why right now, I am looking for a new one. I will also try to check the fuse.
Arhh like that, what a bummer 🙁 I would reach out to plinius Audio, here's the contact link.
