Erratic pitch movement


I'm afraid it could be many things, most likely nothing to do with the pitch control. I believe you have a Direct Drive motor, so that maybe bad. There is a circuit that operates with a microprocessor(computer) IC, called a Phase Lock Loop, which is what keeps the pitch accurate. Anything there could be bad. More more information, or should you have more questions, please visit my website at audioserviceclinic.com. I may be contacted through the website. Thank you.

Recently purchased used Panasonic SL-HM42 turntable. Works, but turning a little slow on 33rpm (30-31rpms) says DC Servo System on the front. Don't see any set screws on bottom. would like to get platter...


How to tweak the playback speed on Panasonic SL-HM42 turntables

You will need:

  1. 1x small Philips screw driver
  2. 1x small flat-head screw driver
  3. An ear for correct pitch and a little bit of DIY skill!

Step 1 - Remove the wooden base plate

After ensuring that you've removed the the rubber turntable slip mat and securely docked the turntable arm, carefully flip the turntable over onto its lid to expose the wooden base plate, as per below.

Using the small Philips-head screw driver, remove the screws holding the wooden base plate in place, then gently lift the base plate off the turntable.

Step 2 - Expose the pitch adjustment screws

Once the wooden base plate is removed, you will see the speed-controller circuit board on the right-hand side.

To expose the the two speed/pitch-control screws, firstly remove the screw holding the speed-controller circuit board in place, then gently lift the circuit board up on the free side.

Step 3 - Correct the turntable playback speed and pitch

The easiest way I found to correct the playback speed was to flip the turntable carefully back into the original position, allowing the speed-controller circuit board to hang free as shown below.

Next, play a record that you know well and are able to tell when the speed/pitch is correct (assuming you have an ear for correct pitch, that is!), then at the same time using the small flat-head screwdriver, gently turn the speed adjustment screw(s) to adjust the playback speed up or down until the correct playback speed and pitch is achieved (or at least until it no longer annoys you ;).

Turning the screws clockwise (to the right) will increase the speed/pitch, and anticlockwise (to the left) will decrease the speed/pitch.

NB - Both screws allow for fine pitch control, so if the second is already at maximum speed, you can use the first screw for additional speed.
Step 4 - Reassemble the turntable again

When you're happy with the speed of your turntable, remove the record, the mat again & locking the turntable arm, replace the screw holding the speed-controller circuit in place (as per Step 2) and then finally replace the screws holding the wooden base plate, as per Step 1.
Happy listening!

I am looking for a new needle for a KD-2070 turntable and unsure of what kind to get?


The answer is on the cartridge. It should have a make or model number on it. You can type that into Google and the word stylus. You should find the correct type. Sometimes it's cheaper to buy a new cartridge and stylus together. You can then go for any type, as long it will fit on the headshell of the arm.

I have a Sherwood PD - 913 R and the pitch seems to be spinning out of sync which makes the RPM"s not right for 33 or 45 speeds, any help on what could be the cause is appreciated. There is a pitch...


The turntable motor might be the problem, if the grease is old it becomes hard causing the turntable to run slow, by your description we can rule that out since you indicate it runs to fast. therefore it is the voltage that powers the motor with a regulator "keeps voltage constant" or the motor itself will be the problem. The pitch control allows a small change in speed when required.

One of my technics' 1200 turntable's tone gets too high


You can try adjusting the pitch's gain, which is located on the pitch control circuit board. Only problem is that you'll have to take apart your turntable in order to get to that section (its on the bottom).

If that does not work, your pitch might be bad, or one of the main circuit drive IC's might be bad.

Hope this helps some.

My kd-8 is missing the two bolts that keep the legs from folding in when in the open position. What size/thread pitch are those screws?


Expect the bolts MAY be Metric. Try to find a sample and take it to a hardware store like Ace.
