Auto return hits warped records

Post by Mathijs2000 » 19 Sep 2019 21:01

Hi there,

I hope anyone can help me with this. I just got a Technics SLD-303 turntable. I played a couple of records on it. A few of these records are slightly warped. These records play great though.
The Technics SLD-303 has an automatic arm return. When the stylus reaches the end it returns to the basic position again. However, when the arm returns on the warped record it hits the record. This of course is not good for the stylus and the record.
I have already looked through the manual. I could not find anything there. Changing the tracking force does't matter either.
Can somebody please help me with this???

Thanks

Check out Service Manual (not Owners Manual), page 6, Measurements and Adjustments, Arm-lift height adjustment. I’ve never seen an SL-D303, but that looks like it may do the trick.

I'd look at fixing the warped records. Floor tiles, sheets of glass, chopping blocks of the right size can be used to remove warps. Just takes weight and time.

No the records are not the problem. It's just that the edge of the record is slightly warped. I think the arm has to be placed a little higher. Do you know how to do this with this particular turntable. The manual doesn't give me enough info (I'm still a noob in this new hobby).

Records should have no warp. Warp is the cause of the problem. Stylus hitting the warped record is a symptom of the problem. Fix the cause, not the symptom.

Hi, it's very easy to raise the height of the tonearm. First unlock the tonearm from the rest stand then raise the tonearm using the cue lifter. Next push down on the cue elevator until the small screw in the center pops up. The cue elevator is the black "C" shape piece under the tonearm. Then turn the screw counter clock wise to raise the elevator or clock wise to lower the elevator. Hope this helps.

Look in the library for the manual, then look for the height adjustment, it will show you how to raise the arm so the warped records dont get in the way.

If the turntable has been set up correctly, the arm height shouldn't be adjusted. Raising the arm will upset the cartridge angle.

What needs to be adjusted in this case is the arm LIFT height. The service manual should show how to do this. The arm lifter should have a small screw which will adjust the height. If it's not adjustable, you may be able to put something on the arm lift platform to make it taller, without interfering with normal playing functions.

You can not elevate the arm itself on a Technics. It is the cueing platform that needs to be raised. musicmn has the correct fix. Some cartridges need the clearance changed in the manner he described. Not all cartridges are the same height. Ideally there should be a minimum of a quarter inch or 6 millimetres between the vinyl and the stylus tip when the cueing lever is raised.
