Casio AS-120 amplifier with built in reverb. I don’t really know a great deal about this, but I’m assured it’s in full working order and is apparently circa 80’s. Looking online, it says that Casio produced around 100 of these for use with their keyboard, organ and synthesizer systems and therefore s a very rare piece. It’s in pretty good condition considering the age, a few marks here and there, particularly on the very bottom edge at the front (see pics). Comes as seen (no other cables or box) but it’s just a standard power lead. I’ve tested it briefly and it powers on ok. Thanks for looking
