Roland R-5 Drum machine

Anyone know where I can download a service manual for this item? or just have the PDF, please?

Try Roland first, sometimes they have manuals listed for their past products. on their site

Roland’s website isn’t the easiest to navigate, it is split into alphabetical sections. They do have a built in search as well. Each product lists roland available support and accessories as tabs on each product page.

The main directory for owners manuals.
