20 Most Recent Technics SL-1210 Turntable Questions & Answers

Remove the red and it goes quiet? Put the red into the left channel, what happens? Put the left plug into the right right socket, what happens? Put everything back to the feedback, power off and remove the turntable cartridge, what happens? This proves whether it is the cable or the internal electronics of the amp, or the wiring further up to the stylus cartridge. you are the only one with the issue https://www.google.com/search?q=Technics+SL-1210+feedback ..

SOLVED!!! I had the exact same problem after my Technics SL-BD35 had been stored away for years in my attic. The problem is not on the circuit board. It's in the motor. There is a magnet on the motor spindle that is picked up by a sensor to detect speed so the circuit can regulate to the adjusted speed. That magnet came loose from the spindle and was sitting still. No spinning magnet means no feedback to the speed circuit so the circuit cranks the motor speed to max. I used superglue to glue the magnet back on the spindle. TADAA!! Turntable works like new.

Has the tip broken off the stylus?

Enter your make an model into Google search. I have seen a PDF of it you can download. HOWEVER I can NOT say if it is genuine or contains malware. You must download at your own risk.

It seems that is bad grounding of the gear, check i everything is conected to ground. I can also be the quality of the cable, Bad cables can produce a lot of noise, try using other cables.

Make sure there is nothing on the magnet part of the platter. Also, sometimes, the screws that hold down the plastic protective cover underneath the platter might not be seated all the way. Lastly, look at the bottom of the magnet, and make sure that it is in tact, and nothing is bent, broken, or cracked.

Other than that, try switching out the platters from your other turntable, and see if the problem persists. You need to rule out what it is not, before you can proceed with finding out what is the problem. So if the noise moves to the other turntable, you know the issue is with the platter. If the noise remains on the same turntable, then you can rule out the platter being the culprit, and can isolate the issue to the turntable. I've never heard of this, and I've fixed well over 3000 Technics 1200MK2/MK3/MK5 turntables in the past 10 years. I am also considered THE 1200s MASTER. So, I am not sure what could be causing this noise, other than some foreign matter. If your in the NY metro area, bring it on by, and I'll take a look at it, or give us a call, and I'll try and refer someone locally for you:

this was happening last mine with mine aswell i just replaced a fuse then it started to work??One fuse had colouring on it which i did not know what it meant sop i didnt touch that.So have you changed both?

Being the older model, the chances are that the drive belt on the Mk2 turntable has got worn and shiny with use. It may also have stretched a bit. If you are using the tables for 'scratching', the fact that you are holding onto the turntable when the motor is running is placing a strain on the belt that it is not really designed for. I would recommend changing the belt - you can easily find spare belts for sale on the internet

You can indeed parallel it between start/stop button, or buy the unit for 50 euro :) or just read this page http://siber-sonic.com/broadcast/SL1200logic.html , but yesterday i say the kit in an technics webstore and i wondered... why should i put that on a turntable, until i just read about broadcasters:)

You can buy a magnetic cartridge pre-amp separately. Probably will be easier.

The turntable output cables go into the input of the magnetic cartridge preamp. The output ones go into an a tape in or aux on the Onkyo. I'm assuming that it doesn't have a input that says deck on it. Apart from getting some good quality interconnects between the devices it's a very simple thing to do.

you turtable will need a pre amp especially if you have a magnetic pickup cartridge

well" for a start, they need to go into a phono socket, this amplifies them.i take it you bought 2 decks with the intentions of mixing, so you gonna need a mixer.MIXER & DECKS SET UP:1.decks into phono channels 1&22. black GROUND wires, go to GND screw on back of mixer3. RCA master / booth Outputs on mixer to AUX / LINE-IN on amp.(not phono)

The most common cause is dirt on the lens of the player. This can be cleaned off in a verity of ways.

The only place to try, would be Andrews Electronics, in Valencia, CA. It may be discontinued if it's older than about 2 years. Happy hunting.
