myVolts 5.7V UK power supply for Roland devices
This high-quality, low-noise power supply adaptor by myVolts has an output of 5.7V DC and 2000mA max, and centre negative polarity. Tip size is standard 5.5mm outer diameter / 2.1mm inner diameter.
It's suitable for all Roland devices requiring 5.7V and up to 2000mA - anything that needs original Roland part PSD.
