Diagnosing my Yamaha MX-100A

Hello,

I'm trying to diagnose my Yamaha MX-100A - does anyone have a copy of the service manual for that early disklavier? It has been blowing the 7A fuse in the power supply. Replacing the fuse restores function but after a few days or weeks it blows again and the piano is silent. There's nothing obvious from a visual inspection of the power supply (no bulging caps or signs of heat) IS there a common failure mode for this piano?

thanks

Jeff

Did you manage to obtain a copy of the service manual?
Cheers
