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
recently-purchased-used-panasonic-sl-jxgmd5u3zcskalhaccgps5fw-3-20.png

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.

recently-purchased-used-panasonic-sl-jxgmd5u3zcskalhaccgps5fw-3-60.png

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!

My records that are 33 and 1/3 don't play at that speed on my turntable. they sound more like a 30 speed, what do I do


Hello Rosie,

Some turntables have a pitch adjustment feature which allows you to speed up or slow down your records. The adjustment controller is usually a slider or a wheel somewhere on the turntable and is usually labelled "Pitch" "Adjust / Adj" or "Pitch Adj".

Please check for this feature on your turntable then get back to me if you are unable to find it. Please include the brand and model number of your turntable.

Hope this helps.

Regards,
BElectric

This turntable goes to fast


I am sure you meant "TOO" fast...please be more specific. Remember, we vannot see your turntable from here, so "this turntable" doesn't help us much.
I have no idea if there's a pitch adjust on it, if it's belt or direct drive, DC servo or stepper controlled, nothing. You need to tell us that "My turntable model X by company Y is turning Z% too fast" filling in for x, y and z. if it sounds like it's just a little fast, z might be 5%. if it's going twice the speed it should, then z might be 100% - give a best estimate for Z but be accurate with everything else.

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.

My stanton t50 turntable plays too fast even when the pitch fader is at the slowest speed


You need to calibrate your pitch control. This requires a small precision screwdriver (similar to something you would repair eye glasses with). If you look under the turntable where the pitch control is you will find 2 small holes, 1 marked 33 and 1 marked 45. Turn the turntable on and set the pitch control lever to zero pitch. While the turntable is spinning insert the screw driver into the pitch calibration hole under the turntable and twist the potentiometer back and forth until the turntable pitch is zero (I believe clockwise is faster, counterclockwise is slower as you look up from the bottom of the turntable). This is a fine tune adjustment and will not require much turning to adjust the speed (1 or 2 mm's) either way should start to bring you into zero pitch. The platter speed can be verified by the little dots on the rim of the platter. They should appear stationary in strobe light on the power switch when you are at zero pitch. When you are adjusting the speed you will observe the dots on the platter rim spinning clockwise and then counterclockwise as you adjust the fine tuning. Fine tune the speed until the dots appear stationary and you will be back to zero pitch. You have to adjust the turntable at both speeds 33 and 45 using the correct fine tuning hole under the turntable. My personal experience is it is easiest to do this with 2 people. 1 person to hold the turntable level and running, while the other adjusts the fine tuning. Hope this helps.
