Could you explain this, please?

You list a TechDas Air Force 3 as your turntable in your system, but according to a 2018 TAS review, the TechDAS has an "AC synchronous motor". So is this DC cable for a different table? If so, maybe you could include a picture or two where the DC cable terminates at the table, and we can go from there. Thanks.

  TechDas been gone for a while. Now it's SpJ a Luce with Dereneville DAE-01 motor,
  Which is DC and takes DC 2.1 connector

    Then I would add a radial lead cap at the 2.1 mm DC barrel connector, being sure to observe correct polarity and voltage requirements. A low ESR,
    1,000 uF Nichicon will work, and cost you less than $1
    
    What are you using for a DC power supply? There's possible room for improvement there, depending on what you're using.

      Could you provide some details on how to connect that resistor?
      And what purpose does it serve?
      I'm using Hewlett- Packard E3616A Linear Power supply.
      I've tried a few "audiophile-grade" LPS before and all of them hummed more than the HP.

        I suggested a capacitor near the load, at the end of your fifteen foot DC cable. This would be to further reduce supply ripple/noise. The configuration would be standard, positive to positive, negative to negative.
        
        You may not even need it, but as noted, they're only about $1.

        I meant "capacitor"
        
        I was just making sure we were on the same page (nt) - 1973shovel 07:36:34 10/15/23 (0)
