The speed adjustment on turntable does not make the speed correct, it is running to fast for a 33 or a 45. A store mentioned making adjustments on the underside of the turntable, with a screwdriver, there are three areas to do this. Which one should I pick? The ''holes'' say SW, L.IN, the other says RET
Great detective work.
Let's collaborate on this for the benefit of others who may have the same problem.
L.IN should be the point at which the Lead-In groove on the LP would be, where the tonearm will drop to play an LP
RET should be the point at which the tonearm will lift up and RETurn to its rest at the end of the LP
That leaves us with SW. If your source is right this will affect the Speed. I can't imagine what the W stands for.
Since this turntable lacks the traditional strobe light and dots along the platter rim for determining if it's on target speed-wise we have to improvise and make a Strobe Disc.
It has radial marks on it and you place it on the turntable like a record. The lights in your room running at 60hz will make it appear to be stationary if the speed is correct; slowly creeping CW if too fast; CCW if too slow.
Here's a link to a PDF from which you can print your own disc... http://www.extremephono.com/ftp/60Hz.PDF
Here's what you do. Lay the trimmed Strobe Disc on top of a record while it's playing one of the outer tracks. This is because the stylus imparts some drag so we want to factor it in.
Then adjust the screw exactly one turn Clockwise and note how the speed has changed. Trial and error should get you to where you want to be.
Use David Dunn’s link to the strobe disc. Don’t use his advice on how to adjust the speed.
SW stands for Tone arm switch. (Shouldn’t it have thrown a red flag when you couldn’t account for the “w,” Dave?) It controls the point at which the tone arm cuts off the motor for the platter. This is why when folks have been adjusting that screw, their platters don’t stop spinning when the stylus returns to its initial position. Don’t mess with it.
What you want to adjust is one (or both) of the screws inside the smaller holes that are also on the underside of the unit labeled “33” and “45.” Use a *tiny* screwdriver, and make *very* small adjustments. A little goes a long way.
yes, Rob Short is correct and David Dunn is wrong. Don't touch the SW screw or you'll have your turntable running endlessly. Use the tiny screws that are inside the motor, behind little rubber grommets that are inside the holes marked 33 and 45 under the bottom cover
Hi Michael & Rob! I didn't scroll down far enough on this discussion and have accidentally set my turntable into an endless spin. ????? I've been trying to remedy it, do you guys have any suggestions? I've adjusted the SW several times and still no solution. Any help would be greatly appreciated. Thanks!

Mocamom1 and dunnbiker, you are awesome. The info from both of you was helpful and the solution worked! I was having the same problem where the turntable was going slightly faster than it should be (about 35 ¼) and it was driving me crazy that everything was too fast & in the wrong key!
As someone whose extent of their knowledge of fixing things is “always unplug it first and pay attention to how you take it apart so you know how to put it back together”, I have a few trial-and-error things to pass along for anyone who needs to try this solution, though.
After figuring all this out, my turntable now runs at 33 1/3 and shuts off when it’s supposed to. Woo hoo! Bruce Springsteen now sounds like his ‘ol self instead of sounding like he just came off a hit from a helium balloon. Thanks again, mocamom1 and dunnbiker, and thanks for saving me a $100 trip to the repair shop!
I took my turntable apart to find the 'teardrop shaped' screw you were talking about (the "SW" screw) and also found that when you turn it, it causes two little flexible metal strips to touch and then make the motor work; like you said in a way..
The SW screw is connected to the needle, so when you move the needle, the screw moves with it, leaving those two metal strips behind, fully connected..and the motor goes at full speed, just as fast as it ever did.
I used a screwdriver to see if i could make the metal strips connection "weaker" by making them just barely touch, but it didn't really work that way, its either connected (motor on, at the same speed) or disconnected (the motor shuts off completely).
So I don't understand how this worked for you. The little tear shaped plastic SW screw just turns in circles, it doesn't get any tighter or anything..
But I'm definitely not an expert and if been messing with the motor in kind of weird ways, which actually made it go faster than it started out with. But even with that said, I still dont understand how it worked, because the only interaction between the SW screw and the motor is when the needle is in its stationary position.
That screw adjusts where the switch that starts/stops the turntable motor engages relative to the tone arm’s position. Just set it to where the motor stops when the tone arm is in the “stop” position.

I tried adjusting the SW screw as explained at the beginning of this thread. That did not change the pitch. Further down, I read about the '33' screw, and was able to adjust that to my liking. (You push your tiny flat-head screwdriver very gently through the rubber, let it settle into the screw, and then make a SMALL counter-clockwise turn, like one quarter, if your problem is that the motor was going too fast.)
However, these experiments have left me with a new problem: Now the turntable motor will never shut off. Even when the stylus arm is fully retracted, it keeps going. How do I fix that?
unplug it... =)
Ever figure this out?
Return the tone arm to the “stop” position. Then turn the SW screw slowly until the motor stops again.

I tried to adjust it and it must have messed up the connection like vinylfan said, the motor wont shut off. then i took off the bottom (again, i did before reading this) and tried checking out how the connection works. i adjusted it in a hand full of different ways with the connection fully touching and bearly touching at all and i cant get the motor to stop still.
I had the same problem with the same record player, and I found out that adjusting the SW screw does nothing for adjusting the speed. You have to have a very small flat head screwdriver and adjust the motor itself, which is incredibly simple.
First, you need a very small flathead screwdriver.
Second, look on the bottom of the record player and locate two holes, one labeled 33 and the other 45.
If your record player runs fast on 33's like mine did, turn the screw a very small amount counter-clockwise to slow the motor, then check your speed.
If your record player runs slow, turn the screw a very small amount clockwise, then check your speed.
This will solve your problem.
My turn table doesn't have any screws in those two holes. There are just two little rubber spots. I tried to turn them with a screwdriver, hoping a screw was underneath, but nothing happened.
The screw holes only line up when the arm is in place. Unfortunately, even though this explanation sounds plausible and even logical it is ineffective.

As Rob Short says above, to save yourself headaches LEAVE THE "L.IN," "RET," AND "SW" DIALS ALONE! These do NOT adjust the speed, but rather where the armature must be to drop and raise the needle, and turn off the motor, respectively. Speed adjustment is done using the holes that say "33" and "45" on the bottom of the turntable. Turn them very slowly, as they will adjust quickly.
I tried this turning the screw several times and with the strobe disc and the speed is fast all the time the same one.
So shoul i opend the cabinet? o What
Dunnbiker needs to realize that no one who owns this turn table has ever thought about printing their own "strobe disc". I'm actually amazed that dunnbiker has looked up from the latest Star Trek episode to try and answer this question. I think I'm going to have a "strobe disc" party and invite the wookies and ewaks to listen to my turn table that is playing too slow. Maybe they'll know wtf a "strobe disc" is.
