Speed varying I have a Technics turntable. Out of the blue it's sounding like a drunken sailor. The speed is varying a lot, faster and slower. It's unuseable like this. Ideas? Is the belt too loose? Wouldn't that just make it consistently slower? Thanks! Rick

Could be the belt for the pulleys is stretched a little, or there is something making it slip, or the potentiometers were set incorrectly from the factory . It is normal to have one for each speed. It is unknown if you can access these from the bottom of the unit. Slippage is less likely to be caused by something oily, since it would alternate the speed faster and slower and yours seems to have worked then reached a constant slower speed. Do your 45's and 78's play ok? (yeah I know, does anyone have a lot of 78's on hand)
Your model does not have an outside pitch control to fine tune the speed faster or slower. Another Jensen model JTA-230 does. Entry level turntables such as yours are not speed accurate reliable. After reading reviews on your turntable, it's possible that the belt is the problem. If the slow speed problem had happened from the start, it would be safe to say that the speed wasn't calibrated correctly and you could have returned it and perhaps had better luck with another one but because it worked fine at the start and then now plays slower, it's either the belt or the potentiometer for the 33rpm speed has somehow changed.

Assuming it is a belt driven turntable I suspect the belt has slipped out of position. It might need adjusting or replacing. If you do need to replace it make a note of how it fits, even though it could be in the wrong position. It's a starting point for putting the new one in the right position.

pls ask it here http://vinylengine.com. they have a lot of knowledge
and is the best place for your question

search for same questions , otherwise we keep typing and too fast sping is also the right search.

Found this post trying to troubleshoot my Aiwa PX-E860U-after replacing the belt and lubricating bearings, the speed was off. 33 setting was playing slow. Here's the fix:
1. unplug and flip upside down
2. Locate the two holes marked 33 & 45 where black dots are visible underneath
3. Using a very small flat screwdriver(I used one from an eyeglass repair kit), adjust the speed clockwise for faster, counterclockwise for slower

this is a DIY solution, so not perfect, but it works. I played the tracks along to a Spotify recording to get a good match. Hope this helps someone else!

Hi, remove it and give the contacts a good clean. If that doesn't work it will need replacing. John

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.

if you take off the platter, then undo the plastic board covering and protecting the circuit board...then once you have access to the circuit board...there should be a little blue knob, usually located top right...its basically a matter of turning it untill you are happy with it, unless you have a little mark on the blue knob and the circuit board...if you or someone has done that, then that will be the master setting, of +8/-8 pitch

On the 1200MK2 the pitch control slider is for just that purpose. Disregard the 0 setting and use the illuminated strobe marks on the platter to adjust to nominal speed. When they appear to be motionless you are there. The control on the 1210 may be a knob but the same principles apply.

Panasonic has always been the parent company of Technics. The Technics line was developed by Panasonic (aka Matsushita Electric) back in 1965. Today, the only the DJ arm of the Technics brand survives. The consumer Technics line (like your turntable) have all been discontinued about 10 years ago.

As for the motor, if Panasonic says they have it, grab it. Part number I show for it - #SDMB5E - $19.99
