Roland Cube Street Potentiometer

One of the knob posts on the amp became bent. When I tried to straighten it out, the post broke off. I am trying to find a replacement potentiometer to no avail, thus far.

    BTW, it's a 10K pot, used for adjusting treble. It is light green in color and there are two codes stamped on it. One code is 8D3. The other is 0B10K.

That is the first thing to check. They are most likely inside the circuit board. Remember to replace them with the same voltage and amperage ratings.

SOURCE: roland micro cube fuse replacement

If the fuse blew, it is for a reason requiring repair. Troubleshoot and use a 40 watt lamp in series to limit current until cause of fuse blowing is found and repaired.

Roland street cube won't power on due to battery acid leak


Most likely the acid ate the internal power supply, but if you can dis-assemble it and clean any trace of gunk with a toothbrush and electronic cleaner, including the fuse and it's contacts, maybe you'll get lucky.

My Roland Street cube amplifier has a bad speaker- where can I find a replacement speaker?


Rubber cement is an excellent for minor speaker cone damage but if you feel that a replacement is required, try MCM Electronics online. They carry lots-o-speaker replacements. Be sure to match wattage and impedance (ohms) of the speaker though as these are important spec's.

My roland cube street starts making this really weird loud noise


Hi, Quick Check. Very often the input socket which is soldered directly to the circuit board, will have a broken solder joint. This is common on a very large amount of equipment. Try waggling the plug about and seeing if the noise comes and goes.
Easy fix, re-solder joint. Permanent fix, connect socket to board with flying leads, or fix socket to board with hot glue or epoxy resin.
All the best, Chris the Fader.

Roland cube street water damage repair


What part of it got wet will determine the course of action.

If the whole unit were submerged, the unit may prove more time consuming to try to fix than to locate a used one. However, I have salvaged imersed laptops before. the procedure is not much different- make sure the unit is as dry as you can possibly make by blowing a fan on it for an extended period of time.- Days.

Once dried, use some contact cleaner on the jack contacts and interupts, any manual control and any switch.

You can then apply power. If nothing lights up, check and replace fuses as needed. Also check the power supply board for failed caps or rectifiers.

Once the power supply is known to be functional, systematically check the LCD display and the aspects of the amp that it controls. This board will be the most vulnerable and most likely to be the source of most issues you will encountr.

If the display survived intact, and amp does nto work, apply a signal to the inputs and trace the signal through the amp with a set of headphones set up with test prods. The problem will be where the signal stops.
