M-Audio Studio Monitor Speaker Repair

Subscribe to the channel:    / @allthingsoneplace  

In this video we look at some M-Audio AV40 studio monitor speakers that have developed a humming/buzzing noise. Because they are used to mix audio and video editing, that could spell the end of these units.

But instead, I take them apart to see what went wrong with the AB class audio amplifier and attempt to repair the speakers by replacing the deformed and failed capacitors. This is a common failure point for powered speakers but sometimes can be repaired with a little soldering for a lot less than replacing the whole unit.
