Recently purchased the Roland JD-XI ,found that I needed a different power supply.
Pleased to say that I was able to purchase the power supply from Thomann.
Seems robust it does what it supposed to do. Maybe the length of the power supply a bit short for some, but not a problem for me, as the keyboard is close to the main supply.
I think it is a bit pricey for what it is, but then you are paying for a branded Roland power supply.
Support and advice from Thomann as allways brilliant!!!
