Roland Cube-20x (20w 8" Modeling Guitar Amp) Questions & Answers
Input jack fell inside
Yes, the jack MAY actually be broken. It will need to be serviced. Run cables through the handle to avoid plugs from being yanked sideways and breaking the jacks.
I like the sound of my practise amp but it's not
you can use the record outputs to run the signal into a stereo receiver without problems, though it would likely sound better with a shure sm57 microphone hooked up to a mixing board or other instrument amp.
the record output should be PERFECTLY balanced to hook up to a consumer-level stereo reciever with NO distortion; however, this record output might be too loud for another instrument amplifier or a mixing board; hence, the microphone in the latter situation.
short answer- "yes, but..."
The unit input voltage is 110 volt and was plugged
The winding is center tapped. It generates +/-24.5 volts DC. Based on it being a capacitor input filter, we need a peak voltage about 1 volt higher to account for the droop of the capacitor and the .7 volt drop of one silicon diode...
Since we need 25.5 volts peak then we need that divided by 1.414 RMS out of ONE side of the center=tapped secondary... So our secondary voltage is 18 volts either side of center.
You will need a 36 volt center-tapped secondary. Here is one that would work:

This has two 18 volt windings that you would connect in series and a dual primary you can set for either 120 or 240 input. About $19 US.
Hi. Can I use the second pedal on my Roland BK5 to scale up the key one semitone at a time?
Yes, you can use the second pedal on a Roland BK-5 keyboard to transpose the key of the music that you are playing up or down by a semitone at a time. To do this, you will need to press and hold the second pedal while playing the keyboard. You can also use the transpose function in the settings menu of the BK-5 to adjust the key of the music that you are playing by a specific number of semitones.

I need a circuit diagram for a Roland MA-15D speaker please?
It's a Chinese made Roland and no service information is available as when a fault is found the main board is replaced, eliminating the need for service information.
I would check that it is a stereo out jack and not mono. If it is a stereo out, check that both input phonos work. If they do, replace the faulty socket or damaged pcboard.

MY Roland Handsonic's digital display is gone
Hell,
there is no display on your Roland Handsonic because the screen inverter or screen board panel is faulty. This has to be replaced for you to see your digital display again.
So its either you use it like that without the display or you take it to a repairer for fixing.
Take care.
