- Unscrew the screws on the top and take the panel off. Now it looks like this. The Dong Woo relay we want to switch is located on the middle PCB with the 2 big capacitors. It's the black box up right behind the red, brown and black cables. Right from the amp you see the new relay.
- Most cables on this PCB can be disconnected, which is our next step. Make sure to remember wich cable belongs where
- Unscrew the three screws on top of the PCB and the one that is down under the case. There is also a female screw on top of this screw
- Now we can turn the PCB around, maybe we'll have to cut some zip-ties so that the cables are not in our way. The component that is held by the female screw has thermal paste underneath. We just wipe this away with a cloth. Now we place the PCB so that we can work on the back:
- The relay is now located down left. I marked the 8 joints (mad paint skills, bro!)
- Only 6 of the 8 pins are used, but we just desolder all 8 and put all pins from the new relay in. As the two pins not needed are not connected to anything, this is no problem. So we heat our soldering iron and desolder all 8 joints. If we worked correctly, we can pull the relay out with a little more force.
- Then put the new relay in and solder all 8 joints. Make sure to keep a calm hand so you don't create unwanted connections
- We need to apply thermal paste to the component where we removed the old paste
- Then we put in the screws again and connect all cables we disconnected
- The last part is screwing the panel on again. But before that we may want to check if everything works. So we connect everything and test it
- That's it! Depending on what replacement relay we chose, we spent a few bucks and maybe one or two hours of time
Maybe I can help someone with this step-by-step tutorial.
By the way, the amp and the monitor speakers are pretty decent for the price I paid ;)
See you next time. Rock on!
