Technics sl1210 mk2 motor speed error

SOURCE: speed regulator.

First and foremost, are you located in the U.S.? If so, make sure your unit's voltage is set to 115V rating. The switch is located under the turntable platter. All you need is a flat head screwdriver to turn it to the proper voltage. If it's on 220V, you need to change it. If you are not in the U.S., or it is already set @ the proper voltage rating, your problem could be one or many issues with the drive, and pitch control. There are various resistors, capacitors, IC's and variable resistors, which control the drive. Any one of these could have gone bad on you. Do you have a runaway operation, or is it doing that back and forth movement? In either case, this cannot be self repaired, and you will have to take it to a qualified service center for repair. Cost will run you anywhere from $60-120 - if they go higher than that, they either do not know what they are doing, or they are trying to pull one over on you. We work on these on a daily basis, and should cost you more than that. However, prices do depend on where you live (we are in NYC). Good luck!

Check that your voltage settings are set correctly. This is located underneath your turntable platter. If you remove the slipmat, you will see 2 holes on the metal platter. Rotate the platter till you see the voltage switch, located @ the 9'o'clock position. Make sure it's set to your correct settings (N.America = 115V / Euro = 220V). If not, you will need a flat head screw driver to switch it. Before you switch it, make sure your unit is off and unplugged. After you swich it, it should be ok.

If your still having issues with the speed and the pop-up light, then there is something seriously wrong, and will need to be checked by a technician. Sometimes a resistor or IC will go bad, causing the speed issue, but for the pop-up light - that's usually faulty wiring generally caused by an incorrect replacement.

Did you buy this new or used? Have you had this serviced recently?

Your switch probably went bad. Does it not respond at all? Does the button at least 'bounce' back when you press it? If not, then you might have messed something up when putting it back together.

SOURCE: How old is my Technics SL 1210 Mk2

Here's some information for you. Since your unit is a SL1210MK2, it may be harder to determine the age of the unit:

It is possible to tell the year (and the month) when the SL-1200 was manufactured from the serial number on the back or bottom of the turntable. SL-1200 serial numbers are in two different formats, depending on the date of manufacture. It isn't exactly possible to determine the decade in which the SL-1200 in question was manufactured, as the serial number contains only the last digit of the year. If the year digit is 8, the turntable may have been manufactured in 1978, 1988 or 1998. If the year digit is 0, the turntable may have been manufactured in 1980, 1990 or 2000. One rule of thumb is that old-format serial numbers belong to SL-1200s manufactured during the 1970s and 1980s, while new-format serial numbers belong to SL-1200s manufactured during the 1990s and beyond.
Old-format serial number: NHOJF20765 (SL-1200 manufactured 1982)
The first digit shows the year when the SL-1200 was manufactured. These serial numbers contain no indication of the month of manufacture. It should be noted that serial numbers in this format contain no letters following digits.
New-format serial number: GE4FB001154 (SL-1200 manufactured June 2004)
The first digit shows the year when the SL-1200 was manufactured, while the month of manufacture is indicated by the letter following it. Months are coded as letters between A and L inclusive; A indicates January, B indicates February, and so on.
In addition to the above, all the SL-1200MK2s from the 70's and early 80's have a 4 inch diameter plate where the RCA and ground wires enter the chassis in the rubber base of the unit. The later models have a smaller hole through which the wires enter the unit.

Since this is a direct-drive turntable, it isn't a slipping or stretched belt. You will need a technician with a couple pieces of equipment and some experience/training to find the source of the problem. I suspect the part(s) will be the minor cost of the repair.
