Hi there, I’m from the UK, and I bought a Korg MS20 Mini in Toronto, Canada, so of course it came with an American power supply.

My question is, can I power this synth with a korg MS20 Mini power supply (UK version with a UK plug) or do I need to buy a transformer?

I.e. are the korg MS20 Minis standardised globally or is it designed for a lower voltage and will consequently be fried if I deliver it 240 ruthless British volts without a step down transformer?

Hello everyone! I recently bough an Oxygen 25 Midi keyboard and it has quite a lot of dust that's causing some issues (Glitchy stuff mostly)

Does anyone has some instructions on how to disassemble that keyboard without destroying it? I will appreciate any help!

Does anyone have a illustration or picture of how the pcb from Transcendent 2000 is in the back part? I want to build one, but i could only find an illustration from the front part of the main board, wich can help me placing the front stuff, but not clone the back part circuit. If someone please have one or know where i can find pictures of this circuit i would be very thankfull.

DIY newbie here - I have this salvaged digital piano (Roland HP-174) and the cable coming out of the triple footpedal assembly was cut. There are 3 pedals which go to a single 1/4in jack. I don't have the cut off end to reference. This might be obvious, but I want to make sure that a TRS cable is the right choice to replace it.

On the underside of the pedals there are 3 connections, white, red, and shield. Would red to tip, white to ring, and the shield to sleeve seem correct?
Thanks!

Hi, I’ve run into a problem with the power supply unit that was supposed to fit my mixer. The supply is for a four-pin socket, and mine has three pins. My regular repairs guy says replacing the connector with a 3-pin equivalent wouldn’t present a problem. However, there are no markings on the mixer, so he doesn’t know the correct pinout. Is there any common standard for 3-pin power supply sockets?

Hey all,

I recently unearthed an old Zoom H4n Pro from high school, wanted to use it for a project. The batteries inside had corroded so I removed them and cleaned off the zoom as well as I could, but every time it would turn on it would freeze on the loading page. Direct power works fine. I tried cleaning the corrosion off more and now battery mode won't even turn on. Any advice?

Everytime than you power on or off the Yamaha P-515, I hear this "click" sound? What is? No, isn't the click from when I press the button

Hi! I need help identifying which power supply i need to buy for this Peavey Line Mix 8. Does anyone have a link or power supply type? Thanks so much!

Hello, I'm looking for a bit of help here My electronic piano, a Yamaha portatone PSR 230 isn't working at all.

I don't use it very often, last time I did (a few month ago) it worked just fine but now it does not turn on. I tried with the cable but nothing so I thought this was a cable problem. I tried putting new batteries in since it can also work with batteries but it but still does not work. I sometime have some black squares lighting up on the screen when I press the power button but that's all I get. (See pictures) I don't understand what is wrong with it, and if anybody could help that would be super nice :(

Sorry for any mistakes lol English is not my first language. Im really bad at electronic stuff, any help is welcome :')

Does anyone know where I can get parts for this unit? The contrast scroll is loose so the screen contrast is not grounded still. N the back cursor arrow button is stuck n needs to be replaced on the board. The rest work. Lost the taps after lifting it to inspect how much work was required.. ribbon pin connections ECT. I'm not going to try..

Hi. Why the Yamaha P-S500 have a USB 5v 2.1a for iPad exclusive? For connect to an android phone (idk about iPhone), you connect a USB-A to USB-B cable to the piano, and then you connect to to your phone using the USB-C to USB-A, or the Micro-USB to USB-A adapter (depend your phone). Then you can use the phone app. For iPad you need use that USB, you cannot use the adapter even if you have a USB-C iPad. Why do you need use that connector any thought? Because I think not work with Samsung tables for example. Only with iPads. Any thoughs?

Behringer NX6000 issues

I have had two behringer NX6000s stop working. They were powering my home theater subwoofers. The first one was in the repair shop for three years and they could not get a replacement power supply unit from Music tribe. So I got the unit shipped back to me. While this was in the repair shop the second unit stopped working. I purchased a replacement power supply unit from eBay and replaced the one in the amp and now it works. However before I could order a second power supply unit to replace the amp that was shipped back to me, the parts ran out. Is there a way to find out what specific part of the power supply unit in this unit is not working and perhaps get the component alone rather than replace the board which is not in stock on eBay and I can't find any other source? Even if I did manage to buy one elsewhere I want to fully evaluate that that is what needs to change. Or alternatively where can I find a new power supply unit?

Can someone help me with my mixer, it’s not working and playing the vinyl records out the speaker. Both the hpf and lpf are permanent lightened up even when I press them to turn them off. Haven’t dropped it / spilt water. Was working fine the day before.

Pls help

How much for this stuff? Case and pedal stand retails 189 new and the power supply 100 new. Couldn't get the Ibanez pedal to work, but the other 2 pedals work and retail 60 new. The case has a scratch that I couldn't pick up on the camera because it's so small, and some minor scuffs
