Schmitty1 it sounds like the cartridge you are using may be too stiff for your tone arm. You might try putting a more compliant cartridge in there and see if your problem goes away. I have seen instances where bass on the recording was not enough to set off feedback but get enough bass going in the room and away you go. You might also have inadvertently located your turntable in a node so moving it just a few feet might make it less prone but still given enough volume it will feed back. The primary problem is the resonance frequency of the tonearm cartridge combination which is being excited. It should be down between 8 and 12 Hz. A good test record will give you that information.You obviously have a very sturdy platform. I doubt it is the problem.
Turntable feedback
I was listening to a record on my Rega planar 3 which sits on a 1 inch thick slab of granite which sits on 4 metal vibration isolation points which sits on a tabletop made of a slab of solid hickory that is 1 1/4” thick. Yet through all that I had bass feedback. The feedback went away when I turned the volume down a bit. It was not that loud. I’m thinking the bass energy went right to the turntable and not up from below. Any thoughts on getting to the root of the problem? Subwoofer is a Goldenear which is powerful but I don’t like bass to be unnatural sounding so it is not booming at all. I like it for its detail not punch.
The turntable is in a corner nook so I wonder if there is a standing wave in the nook that could be transferring directly to the platter. Has anyone else had this problem?
Thanks
