I’m frustrated

Can't get an accurate speed adjustment

How can I accurately adjust the speed of the 33 1/3 on my max lp? I want it to be pitch perfect, and just guessing how much to turn the screw in the back is not accurate enough

  • Hi Yuval,

    Thanks for posting. 

    To adjust the turntable speed for playback, use a flat head screwdriver to pry the screw covers off. Adjust the screws to modify the turntable speed. Imageturntablescrewadjustmentsjpg

  • Yeah, but that's not accurate enough, aren't there any strobes or something to indicate if I am at exactly 33.3 rpms?

  • Yuval.
    I agree, how are we supposed to set the thing if the factory can't?
    Never known the likes.
    Mines going back.

  • I hope this helps, but here is my little adventure with this issue:

    The main problem is that they put the adjustments on the BOTTOM of the turntable. So really the only way to adjust it is if you turn the thing upside down. I came up with an interesting way to counter this.

    What I did was put my turntable on my cabinet in such a way so that it is hanging over the edge. You will want to prop it up with something so that your table is level (I found that two gameboy games stacked on top of each other on either side works pretty well) This gave me the ability to adjust the speed in real time while the platter is spinning. Pictured below:



    Now my unit does not have a strobe or any visual cue to go by to see if it is accurate. So to get an accurate reading, I downloaded an RPM app on my iphone. The one I used is just called "RPM" but there are a bunch of them out there. This lets you place your phone on the turntable platter and it uses the gyroscopic sensors on our phone to get you an accurate RPM reading.

    The issue is though that the tiny, itty bitty screws located on the bottom (Again, the BOTTOM? Are you high?) of the unit are so sensitive that the tiniest micro-adjustment makes a really big difference in the speed. The closest i could get this thing to perfect was 33.34. which is not too bad, but still..... This was an awful lot of work and time to get something to "almost good."

    I really hope someone at Ion reads this and understands how asinine of a design this is. If you are using a turntable more than once, you will need to do speed adjustments from time to time. Just put a strobe and a visual q on it... and put a damn knob somewhere accessible. And in such a way that doesn't involve jamming a screwdriver inside of a plugged in electrical appliance.
