I have been enjoying my 2M Red Ortofon for almost 2 years now on my Technics SL-20. I recently changed a squeaky belt on my TT but I have 3 questions:

1) After changing the belt I noticed that the 45RPM records were playing a bit slow. How do I accurately adjust the speed on my TT? I see the adjustment dials, but is there an accurate way to do this?



2) I notice that some of my records are not as loud as others; recently I have come to realize that when I am lifiting my tone arm with the lever, if I do it slowly enough: right before the stylus completely comes off the record the volume dramatically increases. Does this mean that my tone arm is coming down to heavily on my records? How should I adjust this? My counter weight is set at 1.8 and anti skating is set at 1.8 as well.



3) When I am increasing the volume on my Marantz 2230b, once i go past the mid-level, the volume incredible increases to a point where it seems too loud and a bit distorted. Any suggestions? Or is this normal?



Any member reading this local in Philadelphia? Maybe you can help me out sometime this Summer. Thanks!
