    CD player focus and tracking adjustment

    Hi all I have a Krell KPS-28c hi-end CD-player which I replaced the laser since the old one had very low RF output.
    Now the RF level (eye pattern) is about 1.8V peak to peak.
    The problem is it skips like 5-10 times per CD.
    I have been looking into focus and tracking errors and try to diagnose.
    The CD-drive is a TEAC VRDS-7.
    On the focus error testpoints there are some jumps in the waveform while I see not such issues on the tracking error testpoints.
    Anyone know the procedure of an adjustment of this drive?
