Hello,
I have a Systemdek I 900 that I bought new some 20 years ago. It's not been played that much and it has been hiding in a closet for a decade. Now after preamp upgrade, it's out and alive! Plus it's beautiful!
For most LPs, it sounds really great. On some it distorts slightly, most often on the second half of the side. On some it goes into madness distortion, on some "peaks" in the music (where it hurts the most!) like it can't cope with the record at all, always on second half of the side.
Obviously one then suspects the angle is wrong, so I calibrated the angle using a "stupid" protractor from here, several times. Changed force and anti-tracking etc. Things improved somewhat. Got a brand new pickup AT95E and calibrated again, things improved somewhat again, but still not really perfect. I also levelled the table it stands on.
Maybe it simply is not possible to get this budget TT to play without tracking problems?
Like I said, most LPs sound good so it isn't a big problem, and some LPs sound fantastic - BUT it's not easy to relax with the music when suddenly it might... and also I think it indicates that it might SLIGHTLY distort even when it plays well, implying that I might get a big upgrade in sound if the problem can be fixed!
I took some problem LPs to a hifi shop and their TT played them without problems, so it's not a problem with the LPs themselves.
I hear a very tiny noise from when it is spinning (with the stylus off of course), but taking off the belt, the platter is spinning a looong time if I give it a push. So I don't think that it needs oil.
What else could be wrong? What to do?
Thanks
