Speaker Power Brick Broke. Replace with laptop Power brick?

[newtoCaps101]

So I have this 10 + year old Cambridge Sound works DTT2500 audio system which I have been using on one of my computers, everything was working fine up until a few months ago when I started to get this hum from my speakers. It has a Big Brick Power Adapter So I open it up and see a somewhat bulged 6800uF 25V cap! So I was wanting to replace it and while I was trying to pry the PCB board open from the adapter I missed a screw and broke the PCB in 3 pieces.


What should I do to power my speakers now? Could I buy a Laptop Power Adapter with same output ratting and slightly modify the connector to use it?

The information
240v ~ 50hz
Output: 15V == 3A

SO I am guessing its 45Watts? What do I do now? Use a laptop power brick that say 15v --3A ....or....?

I assume you are in somewhere other than the US with 240V power, but just to give you a rough idea

They are pretty readily available, and I'm sure you can get amazon stuff where you live.

Yes, I am outside of the US. I actually found a few 15v 3A laptop Power Brick / Adapters too. But just speculating if it will work? I mean if I can replace my broken big 15v 3A power brick with a 15v 3A laptop one safely, and if it will power my Speakers set? I could just snip off the connector and do something there but other than that just need some advice if its do able and safe

Just make sure you keep the polarity the same. Using a multimeter find out which side of the output lead goes to the negative leg of the capacitor and which to the positive, and remember to check this when you wire it to the laptop power brick, before you attempt to power on the speakers.

Respect this and you'll be good to go.

thanks a lot for the pics and details! I thought that I should give repairing the pcb a try before I put out the $15 to buy a new adapter! started a new topic!
