How do you level your turntable?

Bubble level from hardware store - $3.79.

Rodman99999 Yep, both offered here look like winners. Thanks.

I use a bubble level and a Sears digital level that cost about $25. I guess I am as anal as most of the audiophiles here.

I use a 12" carpenter's "torpedo" level.

Ya gotta level your platter to the best of your ability. When mine was off about 1/3 bubble, I was getting the weirdest phase anomalies and balance problems. On one mono album, the sound seemed to come from from the front window to my left--90 degrees left of the point between the speakers.

Using my trusty Sears Craftsman level to get the bubbles to level longitudinally, laterally, and diagonally fixed all this.

I have a linear TT (LT-30) and am another who uses the Sears $25 digital laser level.
