Class D Amplifiers have taken over the world! Well almost... and repairing these requires some different skills and knowledge than the good old-fashioned Class A/B amplifiers. In fact a little bit of knowledge can be a dangerous thing here. There are some big differences you really need to know about. So if you are new to Amplifier repair, an old hand at repairing Class A/B and similar Amps, a hobbyist who wants to repair your own kit, or just interested in general this is a video for you. Watch it through and you will most likely learn quite a lot. Skip parts and you probably won't. Your choice :-)
