Technics SL-1200 Turntable - Answered Questions & Fixed issues
My technic sl 1200 is distorting. It is not the
Could be a couple of things. Could be the alignment, weighting, tracking or all of those causing this. It could be the gain structure on your mixer is not set and is too high. Maybe that the output of the cartridge is to high for standard mm inputs
Humming on pfl
50hz hum. Turn off most of your home equipment , turn only your table on, if it still hums it\'s your transformer and that\'s too bad for your wallet. And you also don\'t have those led lights which is a fashion statement at the moment on your table, they are not quite good for causing distortion. And in your home are saving-lights. especially with dimmers and lcd plasma tv\'s a major cause of distortion. But a steady , low freq hum is your transformer and i have a stethoscope, not for that purpose:). Then you don\'t have to search. But they ain\'t cheap, the upgraded in 2009 ones.gr richard
Constant speed
It needs to be taken apart. The bottom needs to be removed. Not an easy job if you are not mechanically inclined. There are pots inside that need to be sprayed with contact cleaner. Pots are under the knobs that control the speed. They have holes on the sides of them. You can purchase cleaner at a radio shack or electronic parts store or online.

Whats the font for technics 1200
The closest font I found is "Arial". I based it on the numerals used.
I do belive the fonts for the word "Technics" is different
Motor dont work
Is it a belt drive turntable? If it is then either the belt is off or broken.
Pitch is not working correctly
a) "dirty" main power switch, comes from sparking when power switch has been used a lot (happens also with some CD/DVD players - makes them loose some power - consequently, focus and/or spindle will not work properly). Try cleaning it up or replacing it (bypassing it will tell you if the switch is really the problem).
b) bad contact on the speed control slider (try moving it while slightly pressing it downwards, see if there is any change, if there is, have it cleaned up or replaced)
c) a problem with electronic speed control, possibly a loose solder connection or a bad capacitor somewhere in the speed control circuitry. If the circuit has fuses in it check if they are all ok. I once had a problem with a turntable that had a fuse "partially" blown (people were using the turntable a lot for "scratching" which overheated the fuse but hadn't blown it out, yet it changed in resistance from zero ohms to a few hundred ohms - the turntable began to **** and the speed was changing).
d) none of the above, it could be something else that i can't think of right now
hope ya get it workin'

My Technic 1200's are only playing out of one speaker at a time.
Clearly there IS a setup issue. Take serrato out of the loop for the moment and the mixer. Plug each deck (one at a time) into a hifi with a MM Phono input. Are you getting stereo? If yes, you know the decks are ok. Now reset the mixer completey. All eqs and pans including volumes to 12 o clock position and volumes to 0.Make sure you connect deck one to a red and white of one phono input channel. Do not use 1 channel from phono and 1 from line. Use both left and right of the phono chanels.Ok, now hook up the mixer to the amp. Keep the x-fader on channel 1 and concentrate getting a good stereo signal from this one chanel. Now do the same for the other cahnnel.This should hae helped you to get up an running, if not narrow down the problem.
The speeds will not match
can you be more precise. At the moment it sounds like you cant beat match. that is not the turntable's fault
I have turned my technics
you changed it back and it doesnt work? theres a little switch that is 120 or 240 or something like that US is 120 uk is like 140
I own a SL1200 MKII
Use the slide on the pitch control to move forward or backward until the dots stay steady. If it is a little old the quartz control won't work as well.
