Kini speaker tersebut rusak karena ada pin dari conector 7-mini din nya putus dan kabel audio utamanya yang dari sub-woofer ke Satelite(yang ada potensio on/of, volume, bass, treble)terkelupas karena digigit tikus. Yang ingin saya tanyakan, apakah Pak Jimmy tau toko yang jual conector dan kabel tersebut..? Dan apakah Pak Jimmy tau jalur/urutan kabel tersebut tersambung ke conectornya, karena rencananya saya akan sambung langsung di board PCB-nya yang ada di dalam box sub-wofer. Terimakasih Pak atas bantuannya Pak Jimmy Yang Terhormat dan Baik Hati

Apart from taking Jimmy's time with all the doubts :) I recommend everyone(with some skills of soldering) to do this, not only will you have your speakers with better component quality as it will make you feel very very good doing this projects : ] When i did this i bought some not so expensive components and believe me, it feels good knowing that your beloved audio system has new components inside, it's like a revival of something you really like : ] Well this is more of a love letter than anything else, just wanted to share some love with all of you. Again, hope you are well Jimmy and kudos to you for all the support. Best wishes, Diogo : ) Hey Jimmy,

Now it seems that the crackling noise has disappeared totally. I have been listening to the MX5021 for the past few days and so far still no noise yet. :) I didn't really do much to the overall circuit except that I did try to reflow or resolder many on-board components and even the SMD components. Maybe that solved the noise problem. Thanks. Cheers, John Hi Jimmy,

Can start to play guessing game, by changing the connection from left-right and vice versa. Could be easier if you have good equipments, though. Thanks. Hi John,

Any ideas what might cause it? I have changed all the electrolytic caps and opamp ICs to OPA2134 on-board.. Is it possible caused by faulty TDA7433 audio processor chip? I have tested the TDA7265 power amp IC by connecting both inputs to right channel output from opamp and I noticed no crackling noise at all on both channels.. :( I have also added few 0.1uF bypass caps around few opamps which have missing bypass caps but the problem still persists.. So anyone has this prob before and manage to solve it? Thanks.. Hi Jimmy,
