Hello, my pitch control on the turntable doesnt hold its pitch anymore, how would i go about by fixing this please? :)

The pitch control need to be cleaned. You will have the remove the bottom to do this. It will require servicing. It could also be PCB board that that controls the pitch or a bad motor.

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!

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,

Hi!
Make shure that is a 50Hz turntable. If you connect a 60 Hz turntable in a 50 Hz system, the result is aprox 28 RPM in the 33 RPM position/

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.

try replacing the drive belt with brand new one and see if this improves the situation

Either the pitch control is damaged, or your drive system is damaged. Unfortunately for either case, your going to need some professional assistance.

Sorry I couldn't be of much more help.

LED probably burned out, or installed reverse (+/- reversed) - Or, you installed a clickless (MK3/MK5) pitch control in an MK2 turntable.

Did you do this yourself? Or did you have this professional done? If professionally, and the LED does not work, ask for your money back! This is electronics repair 101!

If you did this yourself, then more than likely you installed the LED backwards. The longer lead is the positive lead. If the LED did not burn out, you might be able to just remove it and switch it around. If it does not work, then it probably shorted (more than likely). Also make sure that none of your solder is touching. This could cause a bad short to your entire turntable. So you want to becareful.
