Vermona E-Piano (Burned out AC Transformer) what are the output Voltages??? HELP!

[mydemons]

Hi!

I need some help to figure out the output voltages of the AC Transformer of the Vermona E-Piano because yesterday it just burned out as you can see from the pictures...

I know that it has one output of 24V to the lights of the On/Off Switch and Sustain (because it's written uncerneath them), but there are two others that I can not figure out, the 2 black wires and the 2 blue wires that connect to the mainboard (orange board)

The technician told me that this is all he needs to know in order to replace the AC Transformer, but since he is an electronic specialist and not a old retro keyboard specialis, he has no idea of what kind of voltages are generally used for powering the boards...

please help!

thank you so much!

Joao.

I found schematics of a Vermona piano in my files, but I am not sure, whether it is the same you have.

In the picture you can see the power-unit.
