Noise when playing vinyl

I just bought a used Rogue Audio Sphinx integrated amplifier which appears to be in very good shape, and connected a Micro Seiki DD30 turntable to it which I obtained used in eBay. The turntable seems to be in good shape, and works fine. However, when I first turn it on and start playing an album, there seems to be a rather loud low frequency noise which makes the woofers in the speakers vibrate wildly, and even makes the needle skip. I turn down the volume, wait a few seconds, and then can resume playing without further problems. Anyone have any idea what is causing this and how I can repair it? Thank you all in advance!

A little test. Without the turntable spinning, place the cartridge on a record as if you were going to play it. Slowly advance the volume control. If, at some point, you hear howling out of the speakers, turn the volume control down very quickly. Post back into this thread with the results of this test.

If this happens, you have acoustic feedback. There are two paths for acoustic feedback. Structure borne means thorough the stand that the turntable is mounted on, and air borne means through the air.

Its sounds to me like a major cartridge tonearm mismatch. Try a Cartridge that the tonearm likes. This is most likely why you are having so much woofer movement.

Do you know if your TT has a built in phono preamp? If you are not sure, plug it into a line level input and see what it sounds like.
