If you have some free time, print the Cube 20 schematic you have and check it part by part with the actual PCB, renaming parts if needed. The final check is to apply test probes at power plug blades, switch amp on and read primary DC resistance.Įverything unplugged of course. As Enzo would say, to start measure if your power transformer primary didn´t open, follow both primary ends until they reach the wall plug blades, maybe some connector failed or is simply poorly plugged, no damaged open power switch or fuse holder or mains plug in the path, etc. In any case, maybe parts labelling is different, just add a 5 cent resistor at the beginning and everything after gets shifted 1 up, but actual schematic should not change that much. I think I have the plain Cube 20 somewhere but will check anyway.

Even the component labeling appears completely different.Ĭan anyone assist an old soldier in locating a schematic or service manual for a Roland Cube 20X amplifier? Thanks in advance for any assistance anyone might provide. There are schematics floating around the Internet labeled 'Roland Cube 20' but they appear to be significantly different that the circuitry I'm looking at in the 20 X. I would love to repair this Cube 20X and use it for myself, but in days and days of searching, I've been unable to locate a schematic diagram for the Cube 20X. I'm an experienced, retired electronics technician (military veteran) and now own a computer store/electronics repair business.

Unfortunately I can't go any further without a schematic diagram. I've already done all of the preliminary trouble-shooting to eliminate any of the 3 fuses and anything else obvious, without success. I have inherited a lovely little Cube 20X that isn't powering up. Musical Instrument Amplifier Roland CUBE-20x Owner's Manual.
