I have a Techniques SL-23--just bought two brand new belts. One runs too slow and the other too fast.

How do I fix it?

You just need a new belt, they're around 20 bucks. Buy them in pairs, or threes. They stretch out about every seven years.

SOURCE: all my vinyl sounds warped on turntable

Most common problem is the belt getting soft, especially if it has sat for a long time. It will get a weak spot where it sat on the drive pulley and every time the turntable goes around and hits that weak spot it will slow down a little making it sound like a warped album.

The belts are usually very easy to replace. Usually just lift off the turntable or there might be a small clip on the center pin, then it lifts off. Replacement belts can be ordered from several places, as shown in this search... http://www.google.com/search?&q=SL-B200+Technics+turntable+belt

SOURCE: I need to put new turntable belt on a Technics SL-B200

The belt goes underneath the turntable platter. First you attach to the lip on the bottom of the turntable platter, then you put the platter on the turntable. You'll see some holes on the platter, after you put it on, just rotate the platter, until you see the motor shaft, then pinch the belt around the motor shaft.

SOURCE: Changing the belt on a Technics SL-3 (Linear tracking) turntable

Instructions on installation of your drive belt - this also applies to other brands as well - however this belt is only for the Technics models listed above:

Remove the turntable platter off from the turntable
Remove the old/damage belt
Wrap the new belt underneath the turntable platter - you will see a small lip on the bottom of the platter. Wrap the belt around this lip.
Put the platter back on the turntable
The turntable platter will have small holes, rotate the platter until you see the motor, and the motor shaft.
Pinch the belt, so that it wraps around the motor shaft
Turn on and enjoy!

I have just bought a pre-owned Technics SL BD-22 turntable and the speed is variable - when I adjust the pitch adjustment wheel it seems to get worse. On listening to familiar music it seems to be running...

Have a look at the bottom of the turntable. This type of turntable often have speed adjusters. They might be covered by a sticky label or something. If you can't see that go inside by removing the bottom and look inside for them. There should be two, one for each speed.

Pitch Control Problems

More than likely the pitch needs to be calibrated. Although not very hard, I would suggest getting this done by a professional, as it does require opening up your turntable.

Here are instructions - TECHNICS PITCH CALIBRATION

If you cannot perform this, then find yourself a good technician who knows what they are doing.

If this does not work, more than likely either your pitch control, the pitch gain, or one of the IC's need to be replaced - at this stage, only a qualified service tech can help you.

Good luck!

I didn't touch the pitch adj control, i didn't touch the reset button, i just put on a record press play then it run sometime fast and slow and fast and slow and..

This is an issue with the main drive circuits. You have what we call the 'washing machine' affect.

Only a qualified technican can repair this for you. Not too costly, if the tech knows what to look for. If not, then he will spend many wasted hours trying to find the damaged circuits. Make sure you explain the issue to them and ask if they've fixed it before.

Panasonic automatic turntable model sl-hm42

I'm having a similar issue - except my panasonic sl-hm42 platter is moving too slow on 33 1/3 settings (don't have any 45's to try). It's a DC model, so I would think there would be some kind of pitch control settings or screws somewhere on it but I can't seem to find them.
Does anyone know if it's possible to adjust the pitch on this model turntable? Thank you!

Broken pitch control

Yep, time to replace the pitch control. You can attempt to do this yourself, however good soldering skills are required (not the time to learn). You will have to desolder the old pitch control, and solder on the new one. Which is why I say, now is not the time to practice soldering on your turntable. You could actually cause more damage.

If after replacing the pitch control, you still have the same issue, then there is something wrong with the drive on the unit. The drive is controlled by various integrated circuits (IC's), and they are known to short out every now and then. The problem is isolating the correct IC. FYI, Technics is starting to discontinue parts, and 1 of the main IC's on this unit is no longer available (IC302 - Nand Gate).

You can order the PITCH CONTROL HERE.

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.
