WHEN I TRY TO USE ANY ORTOFON CARTRIDGE I GET FEEDBACK WHEN I PUT IT ON THE TONEARM BUT ON MY TECHNIC 1210 IT DOESNT HAPPEN BUT IF I USE ANY STANTON CARTRIDGE IT IS FINE? WHY WOULD THIS BE? ALSO THE TONEARM ON MY 1200 IS REALLY LOOSE I MEAN THERE IS ALOT OF PLAY IN THE ENTIRE ASSEMBLY, IS THERE A WAY TO TIGHTEN IT UP OR DOES THE ENTIRE TONEARM HAVE TO BE REPLACED? THANKS, DAVE

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

Nice , i just received my tonearm wire for a technics. mk5
First question , Which tonearm are you try to put in and why, since if you want a better sound , sell the unit instead of useless replacements and do you use the phono or line out...

Soak a q-tip with rubbing alcohol and stick it into the contact area of your tonearms. Rub the contacts thoroughly. The contacts themselves are spring loaded, so make sure all four are all the way out for full contact. Clean the stylus connections with alcohol as well, and you should be good to go. I also use Ortofon Concorde stylii on my 1200s and have never had a problem.

I've seen this on technics turntables before. Try tightening the screw on the arm.

I think we need to do more diagnosis. Did you try swapping the channel cables Left-to-Right so you're sure it is in the TT and not in your Phono preamp?
If it's still in the TT and always on the same channel with two different cartridges you probably have a wire problem in the tonearm/shell or interface between them.

Hi,

Please re-check all your other equipment, as its highly unlikely to be the 2 turntables at fault, let me know how you got on.

Regards.

More than likely either your RCA cables need to be replaced, or the tonearm is damaged. Do you use Ortofon Concorde cartridges by any chance? If so, the tonearm could be faulty, or the connection from your cartridge to your tonearm might be loose. Just tighten the nut a little bit more.

If you use different cartridges, then the issue is probably your RCA cables and need to be replaced.

IN either case, professional assistance is highly recommended.

Since you've already replaced your RCA cables, and tried different cartridges, the only other thing that would cause this type of issue is your tonearm. It's probably on it's way out, and will need to be replaced shortly.

You can obtain a replacement tonearm HERE, however, it's rather difficult to replace the tonearm without experience or knowledge on soldering.

Good luck!

The only thing I can say is to make sure you set up your cartridges correctly - click HERE FOR INSTRUCTIONS on BALANCING YOUR TONEARM properly.

If, you've balanced your tonearm, and set up your cartridges correctly, then you should not have any problems. Unless, your tonearms are damaged. But this is highly unlikely. I just think you need to balance properly.

Another note, Ortofon Concorde have a design flaw, in that they don't connect very well to the Technics tonearm. The Concorde's, have short and stubby connections on the rear, making for poor connections to the tonearm. Ortofon has addressed this issue by releasing the Ortofon OM series cartridges, and mount them to standard Technics Headshell.

If you still can't figure this out, feel free to give our techs a call 24/7 @ 1.866.668.1596 ext 1 - they can walk you through setting up, and properly testing your tonearm to see if it's damaged or not.

More than likely it's your RCA cables, or it could be a tonearm or cartridge issue. First try and swap out the cartridges on your turntable, and see if the problem persist. If it does, then you can narrow it down tot the tonearm and RCA cables. Since the RCA cables are easier and cheaper to replace, I would suggest doing this first - You can try to do this yourself, however soldering experience is required. You can purchase the parts HERE - and install yourself, or try to find a reputable service center area to replace the cables.

A word of advice, try not to use the original RCA cables that are installed with the turntables, as they aren't of the greatest quality. Try and put a better brand, or use the MOGAMI cables, available HERE.

If the problem persists, then the issue with your tonearm, and replacing the tonearm involves a lot more in-depth work, and I would only suggest having it done by a profession. You can buy the part HERE, and bring it with you to the service center, to minimize your cost.

There is nothing else that would cause this kind of problem except one of the 3 (or combination). So, by a process of elimination, you'll solve the problem.

Have fun!
