I need a tonearm replacing on an SL1210 MK5 turntable, the anti skate spring is busted I think? Need somewhere in Australia, preferably brisbane.

Sounds like to much anti-skating with an old stylus. That can pull a needle back over and over again around the center of the record.
Try setting the anti-skating at 0% and see what happens. Also set your tonearm height to level with the platter. These may not completely fix the problem (may need new stylus tips) but shout make a huge improvement

I’m happy to help further over the phone at https://www.6ya.com/expert/erik_149c4c1c216e42f2

Hi, Assuming the the turntable is on a level platform and that you have "adjusted the weight and anti skating correctly", might it not be just the styli/cartridge that's left in question? Visually check the styli/cartridge assembly, look for unevenness of wear on the needle itself, compare with a known good styli the angle. On some rare instances, it is the shielded wire inside the arm. Hope this be of some help/idea. Post back how things are or should you need further information. Good luck and kind regards.

I don't know what you are referring to as sub weights. Everything you need is already on the tonearm.First you have to balance the tonearm, then you adjust for stylus pressure and anti-skating. For more information, please my website at audioserviceclinic.com. Thank you.

Get one of those little mini-digital scales that should sell for about $30 or less. Make sure it reads in 0.1 or 0.01 increments. Unplug the turntable (so the platter doesn't spin) and place the scale in the tonearm path. Most tonearm and headshell combos should work well in the 1.0 to 1.5 g range. Weigh the tonearm balancing on the scale about midway through the path (where it would be in the center of the record)

I used a flat plastic credit size card to protect the stylus on the surface. Don't forget to tare the scale to 0. Attempt to calibrate your weight scale adjustment on the tonearm to match the scale while you are at this. Once you have found a setting that works for you, match that marking on the weight scale adjustment on the anti-skate wheel.

You should have a turntable that sounds nice and is also gentle on your records!

Has the tip broken off the stylus?

Basically, like almost any other turntable.

Look up the recommended tracking force for your cartridge/stylus.

Unplug the power to the turntable.
Using the tonearm elevation control, raise the tonearm.
Manually move the tonearm in toward the platter.
Manually rotate the platter ClockWise a few turns to disengage any cueing mechanisms.
Set the Tracking and Anti-skating controls to 0.
Disengage the tonearm elevation control. The tonearm will either float or drop. This is why we have no power, just in case it hits the platter.
Adjust the counterweight until the tonearm floats exactly horizontal. Use the flat portion of the tonarm rest as a gauge.
Return the tonearm to its rest.
Dial in the prescribed tracking force and anti-skating. Play records.

KEEP THE ANTI SKATE AT 0 FOR NOW,then you need 2 balance the tonearm with the rear counterweight so it just hovers at around the height of the platter.now you need to zero the gauge on the rear counterweight being carefull not to turn the counterweight,then check again that the tonearm still hovers.then screw counterweight inwards untill the dial on counterweight reads between 1.5- 2 grams dependin on tracking weight of cartridge.then adjust antiskate 2 whatever u set the tracking weight to.i would also double check with a spirit level ur level surface

More than likely your RCA's need to be replaced. There is no need to open it up, as the ground wire rarely every comes loose. It's held down by a screw & soldered to the circuit board. Unless you pulled on the ground wire.

There are only 3 issues which can cause this:

1) Technics Tonearm - Check the 4 prongs inside the tonearm. Make sure they are all clean (shiny gold), and all protruding the same distance. There are springs behind these prongs, and often times they do come loose over time or overtightening.

2) Technics RCA Cables - This is more than likely the culprit.

3) Cartridge/Headshell - swap out with your good unit. If it works, then your good. Just replace cartridge

With the exception of #3, the other 2 will require assistance from a qualified service technician, otherwise you could cause more damage to your turntables.

Hi...
What model BSR is it?

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.
