I was at a gig last night and found that my pitch was extremely inconsistent. Today I turn it on and it seems to be working fine. I'm afraid I might encounter this problem again. Is there a reason why my pitch would jump form 33 to 45? It felt like I was holding down the 33 button and hitting the 45.
How old are your decks?
common this problem,,,, sounds to me that you have
a dodgy switch probably where you have been using the 45 to pitch up intermittently from 33
this isn't really an expensive fix, though if you have warranty use it!
if you are going to attempt this your self parts are gonna cost about 15 bucks! but get a service manual and take the greatest of care heard a few horror stories which is why if you need an engineer to work it for you out side of the warranty you are probably looking at 70-80 bucks, i fix my mark 2's when i need to ,,,just be sure you have read up b4 you start!

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.
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???
Hi I had the exact same problem!! I was using a 4 gig kingston memory card. I formatted the card to 2 gigs, it still had the same problem, then i erased all the movies and reformatted it again. It seemed to work fine after that. But i have requested a replacement handset anyway due to a battery problem when i turn off the phone the battery still wastes. I got a replacement today. and i also bought a 2gig micro to replace the 4 gig just incase the phone will be having the same random 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.
