Angry 1200's pitch help!!!

I just bought a BRAND NEW set of Technics 1200's MK2 and Im a bit worried that the pitch on BOTH arent working properly. Ive had a pair of second hand technics before and they both feel completely different. I seem to have to do an awful lot more pitch adjusting on these ones when blending and they arent holding together for very long (i usually hold blends for over a minute or two with no such problems). At the minute I cant really compare them side-by side to another deck as only one of my friends have technics but they are the M3D model (UK) and are faulty. Is it normal to get this sort of problem with a brand new turntable.....or is it just me?

My theory

I think that everyone breaks in thier pitch in their own way and that makes any change in the tension seem like a defect. My guess is that nothing is wrong, you just need to break 'em in...

This is a theory and not a lab tested fact JSD540 neither encorages nor condones the breaking in of your pitch, it is only an opinion. JSD540 is not a scientist, developer or proffessional expert in the breaking in or adjusting of your pitch. Your pitch is your pitch and not necessarily the same or likley to react in the same manner as anyone else's pitch, especially the pitch of JSD540.

Sorry spent the day with a lawyer today.

No.

I always believe that would do more harm than good over the long term. Just be patient in a day or two (12 hrs or so) you'll adjust and shortly after they will start to feel better.

no lube!!

Never put lube into sliders. There are certain products that can be used but wrong types will tend to ruin slider. They are carbon tracks and should look after thierselves within reason. Perhaps others could comment on actual serice life of slider, they seem pretty hardwearing to me.

I am surprised no body posts how you actually calibrate pitch on a Technics 1200. You need a ohm meter, a frequency counter and the service manual.

Avoid advice from brain donors (on other forums!)of randomly twisting pots etc to 'make em go fast innit'

A gold star goes to first to post link to genuine service manual, I have such on paper.

Using such should bring all you decks to same spec once the new ones have settled.

Well, they should be fairly well calibrated if new. I have found that on some replacements that i have fitted the lugs holding the carbon track to it's housing have been too tight. This cuased the pitch movement to be stiff towards the centre and loose as it moved to the end. Manually adjusting the lugs that were too tight got the performance back.

2.7k ohm, that's the important one.

I meant calibration of the old would bring relative action of pitch to same or very near to new versions. That is if using three or four SL 1200 together. Thats the theory anyway.

I went through all of Technics after buying a extra one ten years after the other two. All were SL1200 Mk2 though.
