Sony turntable runs slow approx 30 rpm.

Cheapo old all in one midi size unit. bit to good to bin but deck runs slightly slow at both 33 and 45. only leads are from pcb and are power and phono leads from cartridge. thought there would be a small preset pot for adjustment...can't see one. Is all lost? Thanks

    Amazing!! Fixed my own problem. After reading this site though! Turns out adjustment pot is located inside the actual motor, accessed via small hole, covered by rubber dust cover, in base of motor unit. Great, another bit of kit saved from the bin. Now it's running at the right speed can happily donate it to local charity shop. Result.

SOURCE: hum when turntable connected to phono sockets on amp

this turntable absolutely came with a ground wire that must connect to the gnd connection on the amp. maybe it got torn off or something but there should be clues on the back of the turntable as to what happened to it.

once the lead is found it must be connected to the amp gnd connect to get rid of the hum. this might require someone with soldering skilz or what have you in order rig up a new wire.

a tech might have to remove the bottom and solder in a new wire if it is cut or ripped off at the housing. This is common as people forget to unhook the gnd wire from the amp when moving things around.

SOURCE: Turntable will not turn (spin)

It would appear this is a belt drive turntable - here's a link to a site where you can order a replacement, although you may be able to find a cheaper one.

SOURCE: Buzz coming from speakers on phono input

is the wire loose on either end? sometimes the electrical plugs can cause noise due to resistance, so trying different outlets might help too

The turntable is not moving at the right speed; just a bit slow. how can the speed be adjusted up a bit? and what to look for?


It all depends on the type of deck. Direct Drive models are more complex as the motor has it's own control circuit where any part can go wrong producing a slower speed.

Belt drive ones are easier to diagnose. The belt being a bit weak can cause it. If you need to replace it make a note of how it fits.
Oil and dirt, grease can cause problems on both types of deck. Grease can build up and cause it to slow up. Sometimes it might need Oil and Grease to be applied!!

There are speed pre-sets, but if the speed slowing is on all speeds then avoid touching them. On belt drive decks a bad motor can cause problems. But it is not common unless the deck is old.
A good test is the movement of the platter by hand. If it feels hard to push it around by hand, or stops very quickly after a good push by hand, then there is something causing drag.

Why is this turntable running slow?


It depends which type of turntable it is. If a belt one then change the belt, make certain you make a note of how the belt fits before removing it.

Direct drive turntables are more difficult. As it could be any number of faulty parts that cause it.
A build up of grease or dirt in any type of deck can slow the speed down.

A faulty motor on both types of deck will also cause it.

Did any midi sized stereos have minidisc players?


Very few - sony made a couple of lovely units which were very expensive. Check out the details of all MD decks and recorders at the minidisc.org web site which has manuals and repair manuals available for free download along with a lot of information on most of them.

Which thickness setting should I use when playing my 33 rpm records on my Denon DP 297 fully automatic turntable? 17 or 30?


hi,
There are only two types of records available like 17 and 30. the size 30 will be as same as the turn table plater's size. 17 will be in half sized of the 30.
OK

I have a Sony PS-LX210, and need to adjust the speed. Going by the music it's played, it's just a bit slow on 33 RPM (I don't know about 45). I find no external adjustments, but there are some trim pots...


According to anything I can find online, like any decent turntable it has a manual pitch control. Unfortunately, I can't find a manual or even a good close-up picture.

This is the best one I've found.

you should check the fuse on the other turntable to get the correct size, if it persists in blowing you should realy send it back because if you were to use a larger fuse you run the risk of blowing something in the deck, i know its not a great help but its all i can offer

Sony PS-LX250H speed problem


I have a different Sony model (PS-LX-150H) that had a similar problem. I hadn't used it in awhile, and then when I did, I noticed the speed problem.

IF your PS-LX250 is like my PS-LX150, there are small speed adjustment screws accessible from the bottom of the unit. On mine, the two adjustment screws were labeled - one for 33rpm, the other for 45 rpm. Basically I just fiddled a bit with them using a very small precision screw driver until I could verify that I had reached 33 rpm (I used a stopwatch and literally counted the number of rotations/minute after making adjustments.)

Now it sounds right!

Technics 1210 Mk 2 Pitch Fade Problems


You have to understand any sort of calibration meter will only tell you if the pitch control is faulty - or excessively too fast/too slow. If your units are just 'off' then that is a matter of a simple calibration of your pitch controls back to original factory specs. Also, just so you know, the pitch controls on the 1200s are not really calibrated when they leave the factory. They are basically installed, set a default setting, then shipped off. So, you'll often times have 2 turntables with sequential serial numbers, but they are both off.

Here is a tutorial on calibrating your unit back to original factory settings: TECHNICS SL1200MK2 / SL1210MK2 TURNTABLE PITCH CALIBRATION

You can also print this out and give it to the technician who serviced your units. Also ask him what kind of calibration meter, or unit did he use to test? Just curios.
