Re: Replacement Power Supply for QY100
|
Chances are the buzzing is because it is a switching power supply… most of the time this is because a capacitor or possibly an inductor (inductors tend to buzz slightly) might be starting to fail... ? but that could take a long time to happen.
?If it is a transformer brick type power supply then the transformer could definitely make a buzzing sound as well as it ages, but their failure rate is pretty low overall… However they certainly can fail from time to time as well. ? If the buzzing is loud enough to be distracting then it is probably a good idea to replace it... ? in part, because you’re going to end up with a buzzing sound through any microphone you have during vocal recording in the studio (if you have one). ? ?
Speaking of which, I would move it around and make sure it is not caused by interference with other devices on the same line… That is certainly a possibility as well… Try different outlets on different circuits, with and without a powerstrip... ?as it might not be a failing brick at all. I do agree with QYEdit that it probably would never create an electrical issue (on its own) besides the inconvenience of failing at and inopportune time. ? However, It is always is a good idea to check the entire wire line for any sort of worn away or exposed wiring, especially at the ends.? Cheers! --
