Put the pitch slider to +6 and adjust the internal preset until the top set of dots on the platter are stationary.
Check again with the pitch at +3.3 if the dots are stationary then job done!, if not then the pitch slider is worn and perfect calibration won't be possible until the pitch slider is replaced.
Hi, could just be platter not fitted hard down on spindle. I suggest you remove the platter and place it upon a dead flat surface to check to see that the platter is flat. If it is flat refit to turntable ensuring it is hard down on the spindle. If bent discard and replace with new platter.Platters can be ordered for all model 1200/1210 from [email protected]
More than likely the pitch needs to be calibrated. Although not very hard, I would suggest getting this done by a professional, as it does require opening up your turntable.
If you cannot perform this, then find yourself a good technician who knows what they are doing.
If this does not work, more than likely either your pitch control, the pitch gain, or one of the IC's need to be replaced - at this stage, only a qualified service tech can help you.
Check the fuse underneath the platter. You'll have to remove the protective cover to access this area. If your unit has fuses (not all do), it will be on the lower left side. If you do not see anything, then your unit does not have any fuses, and this means that the power transformer (the big grey metal box thing) is damaged and needs to be replaced. I only suggest this be done by a professional service center.
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.
Not sure I understand what you need done. The 1200 has a pitch control, which allows you to control it's speed. Do you want to disable the 33/45rpm function, and assign that to the pitch control, so instead of controlling pitch, you control the RPM? This will put quite a strain on the drive circuits of this unit, but it can be done. Although, not an easy modification, as you will have to modify multiple resistors and IC's on the main board. This should only be professionally done.
There seems to be 2 issues with this unit. Usually when the platter speeds up very quickly, one of the IC (integrated circuits) are faulty and needs to be replaced. However, I've never seen the 33/45 lights come on in addition. So, perhaps the issue started with faulty 33/45 switches, and it then caused a short to one of the IC's.
This will have to be professionally serviced, as it is not an easy fix. There are various circuits on the main board which control the drive, so it's a matter of diagnosing which is the culprit. The 33/45 switches will also need to be tested/replaced.
this one happend to me!! try taking the plastic cover off, under the platter and removing the screws that hold it on if that cures it its because what you ll find is that the screws just catch the underneath of the platter as it rotates. happy mixing
