I just bought a used Technics 1210 MK2, its in great cosmetic condition, however when I turn it on its just a buzzing noise coming from the turntable, should I be worried...? and is there a cure?

SOURCE: technic 1200 mk2 turntable wont spin

need to know if it powers up. Does it try to spin, do you hear it trying to spin? More than likely the on/off switch went bad. No, I am not referring to the ON/OFF knob. THere is a switch this engages when turned. The part is S601. You might also want to replace the Start/Stop switch as well. If neither work, then the issue is on the main PC board, and probably IC101, or IC201 with the problem. At this stage, you will have to have a service tech look at your unit.

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.

It is not suggested that you remove the ground cable. Performing the mod for the ground by soldering a bridge on the circuit board doesn't really do anything either than remove that buzz/ground hum. You've essentially removed the wire that grounds the turntable cabinet to the earth. The buzz is gone, but now your turntable is no longer grounded properly.

I would suggest replacing the ground cable to it's original state, then attach the Monster cables.

If this does not work, then either there is an issue with the soldering to the board, or the board itself might be damaged. You might want to look at the trace paths to make sure none are lifted, or damaged in any way on the board. Another issue might be faulty tonearm wires or not properly soldered wires.

FYI, monster cables are not good for this purpose. I would suggest the following cables:

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.
