Any user would like to let go their ADA 106 working unit speaker system?

Guys I need some help here on my Altec Lansing ACS 45.1

I did fix it myself couple of years ago and I forgot the link on where was the guide of replacing the mosfet IC and sound controller.

So right now I’m not sure which IC need replacement as I’m facing sudden power cut off and buzzing sound.

I can’t recalled do I need to replace the ST electronic chip mounted in the large heat sink, as I didn’t replace the electronic volume controller chip Toshiba before as it didn’t give that problem.

I've found the culprit. The big cap 10,000uf has worn off. That cause buzzing/humming sound.

yeap
