I noticed today that if I crank up the volume during playback on my TT I get a very low frequency hum through the speakers, almost inaudible but I can see the woofer moving like crazy. It only happens while the needle is touching the record.
Is it some kind of feedback? Or some other kind of motor hum? There is a slight hum in the system already, I believe from the ground, but this is different as it is only while playing and only at higher volumes (80-90db) If I turn the volume down it goes away. Most noticeable during the gaps in songs or quiet sections.
I do have it pretty close to my left speaker which is why I'm thinking feedback but curious to hear any other opinions.
