Hi guys!

I've received just an old Roland D-50 which operates at 220v, but I need it working at 110v.
I know that I need to just de-solder the cable of transformer to 120v, but what fuses should I use in this case? This is a picture of my synth's power section.

I would be really grateful for your help.

welcome Navid.Nazarzade

The fuses visible on the PCB are secondary side fuses and should not be changed.

There probably is an externally accessible fuse for the primary side. That one needs to be able to handle about twice as much current on 110V than on 220V - so double its amperage.
