Buzz on phono preamp
Barring an equipment malfunction, buzz or hum is usually caused by grounding problems. If your turntable doesn't have a ground wire you may need to install one from the metal parts of the turntable (and/or motor) to the ground connection on the preamp. In some cases you may need to connect the ground wire to your main amplifier unit. Magnetic fields can be a problem also, the tone arm can pickup hum from any strong magnetic source near by like fluorescent lights or a transformer. While the sound of vinyl records is very pleasurable, solving problems associated with this "obsolete" technology can be challenging.
