How to tweak the playback speed on Panasonic SL-HM42 turntables
You will need:
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 Recently purchased used Panasonic SL-HM42 - recently-purchased-used-panasonic-sl-jxgmd5u3zcskalhaccgps5fw-3-41.pngsed-used-panasonic-sl-jxgmd5u3zcskalhaccgps5fw-3-41.png" alt="recently-purchased-used-panasonic-sl-jxgmd5u3zcskalhaccgps5fw-3-41.png" class="h_mi" />
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 theRecently purchased used Panasonic SL-HM42 - 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!
If for sure there isnt a locking waher or anything keeping the platter down what i do is i put my hands on the platter at the 3 and 9 position. gently start jiggling the platter from side to side it is probably gummed up and needs a thorough cleaning thats probably why it is running slow, keep one of your thumbs on the centre spindle so as not to inadvertantly bend the spindle it also gives u better leaverage to lift it up .
