Disklavier

A couple of things:

- are you replacing the 7 amp fuse with a Slo-Blow type fuse?

- You may have a bad solenoid. Make a recording playing each key 20 times  very loudly, and play every key. Then play it back and see if a particular key blows the fuse. If so, then the problem will be either the solenoid or the driver board it is attached to.

I spoke too soon, It has the US & Canada Power Supply too.  But the piano is playing at the moment. I wonder if there’s some pedal action or code in MIDI files I’ve downloaded that draw extra current from the piano?
