The grounding can be a problem. Try using any kind of wire (you can use RCA cables), or you can touch the tone arm yourself.

    1. The connection between your headshell and the tonarm - check it. The simplest way to do it, replace it with a headshell that works for sure.
    2. The grounding can be a problem.
    Listen if it's pure one channel mono, or can you hear a dull bass noise on the other? Now, use any wire to connect grounding on your mixer (or whatever, you can touch pretty much any big metal thing) with tonearm (metal surface). You can also touch it yourself, and produce stereo output.
    Whatever it is, the wiring for the technics 1210 tonearm is pretty simple, and separated from the rest of the turntable... but maybe you would like an "expert" fixing it for you...


    Worse case scenario is your wires inside the tonearm or the base of it are messed up... but it's not really that much of a problem.

Have you considered the amp to be the problem? The amp has a magnetic cartridge pre-amp, which only the turntables would use, that can fail. It's often a single IC that has gone.

Hi there, i just bought 2 Technics mkii


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&2
2. black GROUND wires, go to GND screw on back of mixer
3. RCA master / booth Outputs on mixer to AUX / LINE-IN on amp.(not phono)

I'd say the cartridge is getting tired. Swap the head shells with carts and test. Cheers john. Styluscity

Distorted sound on Technics SL-1200/1210


You could be getting acoustic feedback from the speakers to the TT's. Lower the volume or somehow isolate them from room sounds and vibrations.

Record only plays through one speaker


If it works on Channel One it is NOT the TT. It's a mixer problem. Define the mixer and what else works or doen't work. have you tried another device on Channel 2?

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.

1 X 1200Mk2deck higher volume / causing spkr not to work..


Problem If you swapped the two TT's would the problem stay with the connection on your mixer? At least then you/we would know wherein lies the problem. I'm betting thge low volume is because you have the phono jacked into a line level input like AUX instead of PHONO.

Typically, what you're describing is a phone source plugged into a NON-phono connection. (Tinny, low volume - classic lack of a phono preamplifier with RIAA equaliztion). A standard old-school tuntable requires a phono preamp that is labeled "PHONO". Nothing else will give it the boost and freq response correction LP's and phono cartridges produce.

Your problem #2 alludes to a channel problem with a turntable running through your mixer. This isn't rocket science. Swapping the two turntable channels around would probably change the apparent failing channel, right? Yes - Problem out at the turntable. No - problem in the mixer. You've already hinted at the source by monkeying with the tonearm wiring. You're on the right track. The tiny multi-colored wires in the cartridge shell are very thin and delicate. Their brass fittings sometimes oxidize and reseating them as you have done usually gives some relief. Kinks in the wires could cause your intermittent symptom. At the RCA end of the tonearm cables, make sure they're seated on with a twist to wipe off oxide.

Problem #3. Is it just bothering you or is there a functional problem, too?

try to clean your fader with contact cleaner and move it many times after cleaning -check your connection plugs(buy it from radio shack near you.

Channels


Could be one of 3 issues:

1) Tonearm
2) RCA Cables
3) Cartridge/Styli

I generally tell people to try different cartridges first. If that doesn't work, then you know it's either your tonearm or your RCA cables. 80% of the time, it's the RCA cables. It's very hard to determine which one it is at this point without opening her up and putting on some new RCA cables to test. If it works, then your good. If not, then you know it's your tonearm, and will need to be replaced.
