Modification to SL-1210 Mk5


Hey there

I have noticed that the pitch fader on one of my SL 1210 Mk5's is no longer auto switching my deck to quartz lock when placed at 0%. However I can still use the reset button to get quartz lock if I want it. I am quite happy about this as it gives me more control near the +_0% area.

Im not sure what has caused this malfunction but I would like to re-create it on my other deck.

I would appreciate it if anyone was able to shed some light on this. In general the decks are well looked after and have not suffered any knocks or bumps. Both are in flight cases. If you know what I need to de-solder/detach inside the other deck to get the same results that would be great.

Sl 1210 mk2 problem spin on 33 rpm


Ok it could be the following of which is a very detailed way to go about fixing it so here we go:
1. Make sure your deck is set to 33rpm & that the pitch fader is at the greenlight or dead center spot. Remove the platter & plastic under covering that bares 5 phillips head screws. ee6d0e64-5572-4814-bdd5-3c288a65f86d.jpg 981b4425-f1bb-44db-8009-96c4f6f7045a.jpg
2. This is what it looks like without the platter & plastic cover.

3. Next flip your turntable over onto a big fluffy pillow to protect your tonearm mainly.

4. Remove the feet & all the screws from the bottom rubber cover. After that simply pull up the rubber cover easy & it may be a little tight in there so just do it nice & easy until it has been separated and completely removed out of the way.

5. Now on the underside of your pitch fader you'll see the board & locate the hole thats in that board & use a phillips screwdriver to turn it to the left all the way until it stops. db1b13b1-7724-4ad3-b6fb-849e4b202cf0.jpg
6. Now flip it over and turn it on, make sure its set to 33rpm & the pitch fader is st to "0" or where the greenlight turns on.

7. Then move the pitch fader in the "+" or positive direction or slide it towards you slowly a couple of increments say until you get to the "+2" the Big Red Dot moves & then comes to a stop again like it was before you moved the pitch fader when you stop on "+2". When that happens leave the pitch fader there turn off the deck, remove the platter and then unplug the pitch fader from its internal connection. a6fb6645-36a8-4b1e-b91c-c72b15b430dc.jpg
8. After its unplugged flipp it bck over again& now you need to bust out your Multimeter & set it to the 20k mark. 87b1f47f-20ee-40f6-b803-9f7559643700.jpg
9. After that then take your 2 contact points and place them on these to solder joints on the pitch fader board to get your first reading. e11add40-cf29-46a9-8030-8ef186bb2662.jpg 6c759cec-641c-4d93-bf6d-5c3702914fd6.jpg
10. Again dont go by what reading I have in the picture but instead whatever reading your mutlimeter gives you & write that number down & now you have to get the 2nd reading.
11. First you must reach underneath & now you can slide the pitch fader back into the "0" position or in the middle again & then repeat the same process you did when you got the first reading by placing your contacts again back on the two solder points and take a 2nd reading.

12. Now while you hold the black/red contacts on the solder points, you take your screwdriver & place it back into that hole from earlier & slowly turn it to the right until you see the reading on the multimeter screen matching whatever the number was that you got on your 1st reading. When they match stop & flip over your turntable & make sure you re-connect that plug for your pitch fader.

13. Now go ahead and put the rubber bottom cover back on with all those screws but leave the top internal plastic cover off still, of course you can put the platter back on but leave that plastic part underneath it off. TO BE CONTINUED...

There are 2 problems with the my deck: 1. The +-0 light for the pitch will not work but everything else about the pitch works fine. 2. The deck will not change from 33bpm to 45bpm, I have replaced the...


Hi, please do this test for me. With the deck running on 33 speed and the pitch control set to 0 use your finger on the platter centre and speed it up manually as much as you can. Doe's the quartz lock lamp come on? If not then open the deck up and loosen off the fixing screws on the circuit board that has the 33/45 buttons. Try to change speed with the board loosened off. If none of the above makes any difference replace the quartz lock neon. Use only original Technics neon. As a matter of interest have you done any mods to the deck? Cheers John,

Pitch slider


usually, when you buy the pitch fader itself, then it comes with the circuit board. Ring up panasonic or a distributor and maybe they stock them, but im not sure why you need just a circuit board...and if u bought a pitch and it came without one, then just give a ring around...at least someone will stock it

SL1210 MK5G PITCH REMOVAL ?


The fader for the M5G's are the same as for the MK5's. As for cleaning, you will have to do it like you did with the MK2, and go from underneath.

Technics 1210 Mk 2 Pitch Fade Problems


You have to understand any sort of calibration meter will only tell you if the pitch control is faulty - or excessively too fast/too slow. If your units are just 'off' then that is a matter of a simple calibration of your pitch controls back to original factory specs. Also, just so you know, the pitch controls on the 1200s are not really calibrated when they leave the factory. They are basically installed, set a default setting, then shipped off. So, you'll often times have 2 turntables with sequential serial numbers, but they are both off.

Here is a tutorial on calibrating your unit back to original factory settings: TECHNICS SL1200MK2 / SL1210MK2 TURNTABLE PITCH CALIBRATION

You can also print this out and give it to the technician who serviced your units. Also ask him what kind of calibration meter, or unit did he use to test? Just curios.

Torque Problem


They actually need to be "broken in". The mk5 uses a different pitch board, allowing you to reverse, pitch up and down to 16, and lock and unlock the quartz. The mk5 is more precise, so its also more sensitive. Notice the notches on the turntable shaft behind the tonearm weight. The mk5  is just make to be finer calibrated.....your decks are fine, and more so probably your mk2s as well.

Oh and also, the infinite lubrication used on technics that was developed in the 70s is no match for the formula developed in the late 90s. Slick!!
