PW1800

Hi, I am in Australia.
Could anyone help me to find a power supply for the Yamaha PM1800 audio
console?

We need a Yamaha PW1800 - power supply.

I have tried contacts everywhere, including Yamaha Aust and cannot
locate one anywhere.
Even a copy of the electrical wiring diagram to get one built would be
very helpful.

Thankyou.
