How to fix your (BOSS) power adapter

Hey guys!
As you may, or may not know, I am a man of many interest.
One of them is electronics. Still, I’m  a bit of a beginner, but I have an interest.
So today I’m going to combine my work as a musician with my brief knowledge of electrical repairs, to bring you a post that may be interesting for may of you musicians out there – because this will happen sooner or later!
(I do apologize if my terms or instructions is lacking – i’m not used to writing tech-stuff in English)IMG_1727[1]


If you’re like me and uses effect pedals to change and modify the sound of your guitar/bass/synth/cat, you may have gotten yourself a reliable AC power adapter, so you don’t have to worry about changing batteries while rehearsing or playing an awesome concert, or just want to cut down on unnecessary expenses (my ME-20 eats 6 AA-batteries  in a couple of weeks if used daily).
However, sooner or later (probably “sooner” if you’re traveling much), your adapter will be worn out and brake, much like any headphones, just at the point of where the cables goes into the housing.
But instead of buying a new adapter, here’s AREKU’s short guide how to repair it!
(note that this will work with mostly any adapter out there – I just happened to have a BOSS one)

What you’ll need:
IMG_1731[1]* hammer
* small flat-headed screwdriver
* soldering iron
* soldering
* electric tape

Step one: Open it up!
The good (bad…..) guys at BOSS decided to not give us consumers an easy way to open this product – this since there is no screws.
The two pieces is clued together, and this is what we need to do:
Find the seam, then place a small flat-headed screwdriver and hammer along the seam until you can bend the two parts apart.
Don’t be afraid to be rough – it may take a bit of force to crack it open, just be careful and observant!

Step two: bring out the goods!

Once you’ve opened the housing, it’s time to take out the circuit-boars, so we can work easier.  It looks something like this once released:

Cute the wire that goes out from the adapter plug, around 2-3 centimeters from where it enters the boars.
Now, flip the board over, it’s time to use the soldering iron to heat up the two spots where the old cable is connected to the board.
Locate these spots:

Now, use the iron to melt the soldering that’s holding tha old cables to the board. It takes just a second, so be ready to yoink these bad boys out!
After, it will look something like this:
Two empty holes.  Just make sure you remember which cable went where!
Now, take a scissor, knife or any other sharp object, and cut of the plastic from the bit of long cable you got over. After you’re done, they should look something like this.

Put some electric tape like shown below so you don’t risk getting a shortage.

Now it’s time to just solder these fresh part of the cable back to the board!
Just stick it in it’s respective hole, and solder gently.
All done!
Now you just have to put the board back into the casing, put the casing together, and enjoy having the juice back in your old stomp boxes!

  1. Pro tip; Try not to cut the small copper cables when you take of the plastics as it can cause trouble 🙂
    I need to buy a solder (thats what its called in english?) too, really handy to own.

    • Yeah, I’m aware of that! Sometimes I get to eager though! But it’s true, you got to be careful ^^
      Soldering-iron is so far that I know the correct name, and yeah, you should go buy one the first thing you do tomorrow! I know that Kjell & Co had/have some great deal on theirs. Just make sure to buy a powerful enough one!
