Question about Technics SL-1200MK2 Turntable

1 Answer

My 1200 is making a loud buzzing noise!

My turntable is less than a year old. When I turn on the table theres a loud buzzing under the plater. It sounded like the "transformer" so I unplugged the table and took off the cover. When I pushed down on the large square box the noise went away but I want the table to perform correctly under normal circumstances. After a while of leaving the power off the noise goes away, but later returns in about an hour of normal use.

My question! Is this large square box in cased in a metal housing the power transformer? Is it easy to replace?

Yes, that large metal box is the housing for the transformer. Not too hard to replace, but if not done properly can cause serious damage to your turntable.

I've never heard of a transformer on these units causing a buzzing noise. Did you buy this used or new? If it's new, it's highly unlikely that the issue is with the transformer. However, we have been seeing some 'unusual' issues with Technics 1200s lately, which we attribute to a decline in quality standards @ Matsushita (Technics parent company).

The transformer can be purchased HERE. There really isn't much to replacing this part, just put it back exactly as you took it apart. Take pictures along the way, to help you if you get stuck. Also take some notes on where each part goes.

If you get stuck along the way, feel free to give us a call. Our service techs are masters with the 1200s, and we can walk you through it: 1.866.668.1596 ext 1

I have a JVC turntable and an old Sansui reciever. Last night I was playing a record, and it stopped playing out of one speaker, and makes a loud buzzing noise. However, when I push the Mono button


You should check the connections to the turntable, it sounds like it might be feedback hum, caused by a wire touching or something like that. Don't forget to check the connections to the cartridge too.

Which thickness setting should I use when playing my 33 rpm records on my Denon DP 297 fully automatic turntable? 17 or 30?


hi,
There are only two types of records available like 17 and 30. the size 30 will be as same as the turn table plater's size. 17 will be in half sized of the 30.
OK

Turntable is slow, especially noticable on 33 1/3 rpm


hi,
your turn table is a belt driven one. The speed turns down when the belt become expanded. you should replace the belt of your turn table. Also put some lubricant in its center shaft ( not from the top lubricate it slightly after removing the plater).

I have here added some video related to the replacement of belt for turntables.
Not the exact for your one,for all the belt driven turntable the procedure is the same
ok

It doesn't work. I have followed the instructions though i couldn't find the EG switch but the table doesn't turn when its plugged in turned on and started.


hi,
check whether you have inserted the belt or not. in new turn tables you hvave to set the belt in proper position before starting use. u have to make the belt engaged with the motor pulley.

I have added here a video which demonstrate the installing of belt in a turn table.

In your turntable you can see the belt under the plater when u remove the plater.
remember one thing after installation of belt before plugging it mains , do the following

1. lock the arm in the arm rest
2. rotate the plater 10 times with you finger (for resetting the start position

Then connect the power release the arm lock insert a record press start

If you need any further assistance from me , feel free to contact me through fixya

ok

Cannot get the platter cover off to change the belt on a l-a21 turn table . how do i do this?


Unplug from the mains power & the amplifier phono socket
To remove the plater: first remove the lid - then after securing the arm, FLIP the whole unit over onto the plater (perhaps resting it on your lap) then remove the all the black screws and the brass ones holding the rubber feet in place.
Inside you will find a tube (actually the "pit" for the spindle) undo the (awkward) retaining screw on the tube. At this pint the spindle is now free and would otherwise slide out onto your lap, so just redo all the screws in reverse order -in particular don't forget the Earth wires.
Then holding onto the turntable and plater - flip the unit back over.
The plater will now lift out freely, taking care to unhook the belt from the drive capstan/motor (on the top left) keep hold of the belt with your two fingers (as you have already lifted off the slip matt ) let the old belt slip free and place the new one on the Flange remembering to hold with two fingers as before. the spindle will slide back into the "Pit" (ensure that the bearing has not fallen out) still holding the belt in place hook it over the capstan and under the speed changing device. Try rotating the plater a few times to ensure nothing is trapped untoward, then replace the slip matt.
Re insert Phono lead and then mains power plug.
Place side one of "Goodbye Yellow Brick Road" on turntable and enjoy :)

New RCAS on Technics 1200 Getting a Loud Buzzing Noise


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:

MOGAMI RCA CABLES

No control of platter speed


One of the drive circuits on the main board are faulty, and will need to be replaced. This is not an easy fix, so you will need to take it to a qualified service center for service and repair. Not an expensive fix, but a little time consuming in isolating the issue.
