My Power Amp is making a scary noise!! Please Help! *SOUND CLIP*
I got a used Yamaha PD2500 Power Amplifier and its starting to make strange noises. It almost sounds like a fan without grease. One time I placed it on a different surface and that noise disappears. I play with a band a used this guy with some passive speakers. Recently the squeaking noise comes on just about 90% of the time.
I also connect it through a Xenyx mixer and today the sound just completely cuts off, I know it definitely has to do with the cable connection if not the XLR socket on the channels. Is there anything I can do? I wouldn't mind opening it up and taking a picture for you guys.
