Tone arm problem

Post by Elastic » 19 Aug 2019 21:38

Hi,

I’ve just purchased a Technics 1200 MK2, but the tonearm is extremely springy. If i try and move the tonearm towards the platter, as soon as i let go it just springs back very fast back to the lock.

Is there anything i can do here?

Any help would be gratefully appreciated.

Thanks
Tom

Hi and welcome to the forum

did you set up the turntable according to the user manual, or did you just plug it in 'as is'?
You can find the user manual here: https://www.vinylengine.com/library/tec ... 1200.shtml
(scroll down to the 'mkII instruction/owners manual').

I just plugged in as is. Something can’t be right though, as soon as I let go of the tonearm it just springs right back rather fast to the lock/catch.

It could be that the tracking force is 'off', and the antiskating spring pulls the arm towards the arm rest. Does it also do this with the antiskating knob (black round knob, close to the tonearm base) set to zero?

Yes, set to 0 or anything. I’m completely clueless really weather I should send it in for a service of pop the hood myself and fix it.

Well that doesn't sound good. The antiskating might be out of whack, or in the worst case the tonearm bearings are knackered, and the tonearm will need to be replaced.

Did you buy it as a 'working' unit?

Don’t even go there, it was sold as working but was damaged in transit.

Is it springing back with ot without a headshell? Mine springs back if there is no headshell attached. Once a headshell and cartridge in on the arm, it behaves normally.

If you bought it on Ebay, you might be able to get your money back?

As you move the tonearm, do you feel any resistance? You should be able to put a finger under the arm on the headshell and postion the tonearm with near zero resistance.

Does this happen when you are trying to play a record, or when you are floating the arm to set the tracking force?

Yes there’s resistance as soon as you take it out of the latch/lock

Haven’t even tried playing a record as it’s impossible, the tone arm just springs back to the latch.

Did this shipping mishap involve a major hit to the tonearm gimbal? It sounds like a full tear down is called for, but I think JR already had it covered. Maybe a refund is the way to go.

The anti skate mechanism could be damaged. Contact a DJ gear outlet as a lot of SL 1200's have been repaired over the years and a few years back you could get a replacement arm if you wanted. They may be able to repair the anti skate mechanism.

Good luck.

Doesn’t an SL-1200 permit examining the workings underneath? It seems like the logical thing to do is observe the underside while manipulating the arm to determine what is impeding it’s travel.
