I have some old speakers in the house that I wanted to test. So instead of messing with the real stereo unit from the 80s, I bought a $30 stereo from Amazon, and new speaker wire.

The speakers sound okay, but there’s a hum coming from them all the time. Even with the stereo volume knob turned all the way down. Is this normal for stereo systems and I just haven’t noticed?

    If the ferrite is filtering a hum you can hear, it’s also filtering parts of your music that you can hear because a ferrite just dampens a frequency range and can’t tell what is and isn’t supposed to be there.
