You need a headshell unit (which is needle etc for the front of arm)
also the felt pad.. also known as a slipmat, you can pick up at dj supplies shops or on ebay..
I need a counterweight myself as my ION turntable also had missing parts when I got it as a gift.
I found a headshell on ebay which is perfect...Turntable Cartridge and Headshell Black DJ DISCO USB on eBay (end time 08-Sep-09 00:11:01 BST)
I havent yet found a counterweight..I hope I will!
Hope this helps in some way..
Hey, I'm having the same problem. I found this with a little help from a small site I found called Google:
Here's what he suggests. I have no clue what it means but I'm sure that it cane be decoded with some manuals:
Technics SL1210 , 1979 ? Intermittent loss of one channel. The headshell was slightly loose on the tonearm and moving inwards would cause loss of one channel. To remove this arm undo the slotted lock ring at the very top of the arm pivot and undo the central pin. The arm with jiggling can then be removed assuming enough slack in the signal wires. Undoing the 2 watchmakers screws near the headshell allows removal of the 4 pin connector. Presumably the wires inside the tone arm at this connector could touch the inside of the tonearm and lead to break in sprung connection. Placed a bit of brass shim in the slack area and pushed back in to wedge tight. Also removed the soft washer on the plug shaft of the headshell.
Check to make sure you have a nice solid connection on your tonearm from your cartridge. The problem is either your tonearm or your RCA (red/white) cables.
Neither are easy repairs, unless you have soldering skills/experience. The tonearm replacement is the more difficult and more costly of the two.
Parts for the unit can be purchased HERE. If you have any questions about testing your unit on the exact cause, please feel free to give our TECHS a call - they are available 24/7 for your convenience @ 1.866.668.1596 ext 1
There are two main things that will influence the anti skate settings.
1) The Headshell Weight and Balance
Firstly, check the data sheet for the cartridge and stylus you are using. It should tell you the correct weight setting which will vary from one cartridge and stylus to another. If the stylus is set too light, it can skate across the disc. This can damage the disc and the stylus. The sound will also be thin and it is likely to distort on high frequencies. If the weight is too heavy, it will not jump but will definitely damage the disc.
If you are a serious vinyl user, get yourself a tone arm balance. This is a device that you place on the turntable and you rest the stylus on a plate which is marked in micrograms. You place the stylus exactly at the correct weight marking and then make adjustments to the turntable settings until the tone arm is balanced. It's easier than it sounds!
If you don't have the data sheet for your cartridge and stylus and cannot find it online, use an old disc that you don't mind damaging, set the weight on the light side and gradually increase the weight until it stops skating.
2) Platter Levelling
Secondly, you need to make sure your turntable us on a level surface. If you are a purist, use a spirit level. to do this.
There are other things that can cause skating and jumping, especially if you use the turntable as a DJ. For example, vibration (caused hopefully by dozens rocking to your music). DJs will often increase the headshell weight very slightly to overcome this and I have sometimes placed the turntables on a thick rubber sheet such as carpet underlay to improve shock absorption.
Hey raz, i've just taken apart and put back together my turn table trying to cure the same problem. I DIDN'T NEED TO!!!! number 1) i think the tone arm is a sealed unit so far as i can gather so if the spring is broken you need a new tone arm. however. Get a cotton swab, soak in malt vinegar and use this to gently push the faulty contact in. The idea behind this is to get vinegar around the contact shaft. This should dislodge the dirt and release the contact.
1) This turntable either has bad RCA cables or a faulty tonearm - in either case, none are easy fixes. FYI, If you use Ortofon Concorde series, they are notorious for causing faulty connections with your tonearm, and eventually deteriorate your tonearm over time. So you might want to think about changing them if you get a new tonearm put on. If you use the Technics headshell, you are fine.
2) This turntable definitely needs to have the tonearm replaced. Once the arm comes loose from it's bearings, it's next to impossible to get it back to factory specs, and you will have skipping issues.
Both will require professional servicing. Check out www.1200s.com if your in the NYC area.

Advanced Tonearm stuff
Tightening the suspension on your tonearm
Some TT's have tonearms which seem to be loose. If you grab the tonearm and pull it gently back and forth and it seems loose you can tighten it. It shouldn't move at all. A loose suspension can severely affect it's performance - from jumping needles to binding.
It's pretty easy to tighten the suspension. You'll need a small flat screwdriver and a large one. Use the large one to loosen the outer locking screw on the top of the pivot point. Now use the smaller screwdriver to loosen up the smaller screw. Put a drop of oil where the bearings are (under that top support on the other end of the adjustment screw) so that it doesn't bind. Now tighten the small screw slowly until it just contacts the bearings. Adjust the tightness so the tonearm doesn't wiggle if you pull on it but leave it loose enough for the tonearm to pivot freely without binding. Adjust carefully and don't overtighten otherwise the bearings will be damaged! When done, tighten up the locking screw.
Tightening up the headshell locking ring
Have you put on your headshell, twisted that knurled tightener at the end of the tonearm as tight as possible and have found that the headshell still moves around? What will happen is that the headshell won't sit parallel to the record but may be tilted as a result of twisting of the headshell. This usually occurs when you change headshells a lot or if you've had your turntable for a while, and can contribute to needle jumping so here's what you do to fix it.
First read 3.2 on base disassembly. Remove the rubber base. There will be this big piece of hard black plastic covering almost everything. You'll need to remove it. To remove the tonearm assembly look for three screws (all formerly under that black plastic) and unscrew them. Be careful not to drop the tonearm when you remove that last screw!
Now, remove the tonearm assembly from the rest of the 1200, and look at the bottom of the tonearm where the headshell is put in. There will be two tiny philips screws there. Get a jewelers screwdriver of the CORRECT size and tighten those up. Put the headshell on and try wiggling it to make sure everything is right. Now put your tonearm back on and close everything back up.
hope this helps
