After several months of looking for the replacement for my piano, a high-end driver mara mosfet, and not finding it in my country; and importing it is excessively expensive, I decided to study the voltages of the original power source of my Yamaha Motif6 Keyboard, and I found that with a power source from a desktop computer I can supply those voltages and make the compensation and maybe send the equipment correctly.

The first thing I did was refer to the Motif6 user manual and find out the exact voltages in each connector of the power supply from the drawings.

Then having these values, analyze that the source closest to working all these values ​​is a desktop computer (use a & 00 Watts). The voltage values ​​were very standard, 12v, -12v, 5v, 3.3v, all with tolerable amperage and within range.

Then remove the connectors from the original motif6 source and adapt them to match the new source. Try to make the new source fit as closely as possible to its new shape and add insulating tape to the connections to avoid any kind of contact.

Made all the connections (in theory it should work), and taken to test, the keyboard turned on correctly, this means that it was correct. It's great has come back to life after a long time in the warehouse. Now to create good sounds and melodies!
