John,

When you said you had a power supply repair firm look at it did they return it to you as unrepairable?  Did they have the schematics for the supply?  The schematics are available  in the maintenance manual from Yamaha.  I replaced the supply in my MX100 II about 18 months ago with a supply from Yamaha.  I would speak directly to their service department and if they have no stock, they would know who repairs supplies for them and could pass that information along.  Hopefully, there was nothing else wrong in the piano to cause the supply to go out.  Have you measured the supply voltages? 

Regards,

Mike
