Roland PSB-120 AC Power Adaptor

The PSB-120 is Roland's replacement power adaptor for older gear built around the PSB-1U family of supplies, including keyboards such as the F-90 and FP-3, the BR-8 digital recording station, and the MC-307 groove box. It outputs a regulated 9V at 2000mA on Roland's standard adaptor plug.

Roland lists it as an equivalent for several earlier model numbers, so it is a direct drop-in for gear originally sold with a PSB-1U, ACB-120, ACF-120, ACK-120, or ACI-120 adaptor rather than a universal third-party substitute.
