I have a speaker circuit board that seems like it has a blown amp. I got the replacement chips for it, but I honestly have no idea how to swap out an IC chip on a board, so I was looking for either someone local who I can pay to swap it out, or a service somewhere around Tokyo that can do it for a reasonable price. A coworker recommended a place to me, but it was around 8000 yen a chip, which seems really steep. I thought maybe yushakobo in Akihabara since they run soldering classes, but it doesn't look like they offer a service to do it for you. Any recommendations are very much appreciated.
