Rumbling ?

When I lower my needle in the grooves music is first to appears....soon to be accompagned (from the first second or some other lime a little later) with a steady rumbling low frquency sound that has my powered subwoofer going wild........all stop the moment I remove the needle from the record.
It did go away a couple of days ago for a while after I had played a bit with the arm's various adjustments
but it is back again.
Any recommendations ?

I had the same symptoms. My problem was low frequency feedback. The final solution for me was using 30 foot long interconnects between the phono pre-amp & pre-amp, which allowed me to move the turn table well away from my speakers. Playing with arm setup & platform weighting & floor mass loading etc. would effect the problem & may be good enough to fix the problem in your case. Others have had great luck with wall mounts for the table. If you think you are getting feedback through the floor you should be able to verify this by pushing down on the table with your thumbs, this should reduce the rumble (but it ain't a comfortable way to enjoy the listening experience). Good luck!

Reading Bigte I decided to move my little P25 well away from the subwoofer closer to my permanent table where the Rega had also been used in the past..........the rumbling have not reappeared since....it's a good start for now,......thanks very much you guys.
