    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?

      Marantz Model 150 Tuner "NULL" Adjustment..
      by Mark R
      I am not ashamed to say this is my first FM alignment I have ever done. I am well versed in electronics and repair. Been doing it for many years on Pro Audio Live sound equipment. Worked on Power amps EQ's musical gear and Large format Mixing Live consoles Etc. But now I can see this is a whole different world when it comes to tweaking this kind of gear. I do have the proper gear like the SENCORE SG 80 and HP Generators and Scopes Etc.

      Look below at Adjustment 12:8. The Null adjustment. I have a Heathkit IM-28 VTVM that was rebuilt and has new Burned in tubes that I used for this...

      Pioneer PD-F1007 CD player not reading
      by Xabi
      Hi guys, I need some help with a CD player. It is a pioneer PD-F1007


      The issue is that it doesn't play any disks. The disk gets loaded, spins up, but it doesn't actually plays. Just keeps spinning until I stop it.

      If I put in the CD the wrong way, it will eject it quite quickly, so the unit at least understands that a CD is in and if it's in the correct orientation, tries to read it, but for some reason it can't.

      I started with cleaning the lens to be sure, but ofc that didn't help. Also the laser is ligthing up at least, so it's not totally...
