Question about Technics SL-1210 Turntable

1 Answer

I've got to be honest...(in response to your question)

..I've never cleaned the pitch controls before...What is recommended? I work at a radio station and our engineers seem up to the task of helping me clean/replace the pitches...do u think i should stick with a 1200 pro though? I mean, these are well-rounded and knowledgeable engineers, just without technic-specific experience. How often and how (process) need they be cleaned?

The need to be cleaned as much as you play them. If you play them on a daily basis, I would suggest cleaning the pitch faders at least once a month. Also, the studio environment is also a factor. Is it a dusty place, or relatively clean?

You can clean the faders out with an air can, and some Deoxit or other contact cleaner. DO NOT USE RUBBING ALCOHOL.

There are 2 was to clean, blow the air can inside the fader, removing any debris, then spraying your contact cleaner, then spray air again.

Or, you can take the turntable apart, take the pitch control apart, and clean the contact fader inside. Desoldering is required for this. But it's a more thorough cleaning.

Or, you can just buy a new fader, and install <-- easiest method!

Stiff Pitch Adjustment


What did you open up? The top of what? If you could be specific, I can direct you.

If your pitch is stiff, try spraying some contact cleaner or similar - DO NOT USE WD40. Use an electrical contact cleaning solution, such as CAIG DEOXIT or CAIG FADERLUBE both work very well, and are good for electronic contacts.

If this does not work, then maybe the pitch control knob/shaft is slightly bent? Any physical damage?

Other than that, there isn't a whole lot you can do, unless you replace the pitch control - Technics Pitch Control.

Pitch problem out of nowhere!


HI Mattgood2

I believe this is a common problem more evident in decks that have a very hard life,
You pitch controls are probably due for replacements so I suggest you take then to the service agents to service them,
unless you know how to do the servicing

I grew up with Decks under my fingertips so I have seen this before and remember the only satisfing fix was a service and the pitch controls had to be replaced,

I thought I would have a go re-servicing myself and found far too many things to cover once the covers were off,

There are many things that need attention on the inside of these decks and the precise placement of each component is vital to the correct operation of this unit,peace of mind really

It takes a small amount of care to maintain these decks,
when they die or fail get a pro to fix the problem.
guess work only makes you look like an "Amatuer"

Please dont be offended (by my words) Ive done it too,LOL
I had a full dance floor and then nothing,the decks got replaced

What have you used to clean the pitch control sliders???

PITCH CONTROL PROBLEM


The reset button disables your pitch control and allows the turntable to rotate at TRUE "0" (zero). FYI, these turntables were NOT made for DJing. They were made for radio, studio, and high end home use. They became DJ turntables, because they were perfectly built for the trade. So, the pitch reset button is more of a function best suited for radio stations or a producer who needs to record or play at a true zero speed.

Now, on to your question...

More than likely you just have to calibrate your pitch control. There are various videos on YouTube on how to do this properly. Just do a search CALIBRATING 1200s or similar. FYI, all the Technics SL1200/1210 MK series are the same inside. MK2, MK3, MK5 - so don't worry if you only find videos on calibrating MK2's or MK5s - works the same on all the models.

Good luck!

The speed on the TT is crystal controlled . If that circuit has got an "issue" the speed wont be right.

Also, try cleaning the pitch slider with stuff called Caig "De-Oxit"

Parts Express or Radio Shack sells it.

Pitch LED not working


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.

If you need any further assistance, feel free to give our service dept a call. We are masters with the 1200s, and fix over 300 a year! 1.866.668.1596 ext 1
