    no, no spills

    i used them 1 friday night they was both working fine then i went to have a mix on the sunday and 1 of them had stopped working

    so i removed the platter & dust cover, changed the fuses but still nothing.

    i tried them 24hours later and at first the deck had a little movement, so i turned it on and off a few times, then left it for a min or 2.

    then it started spinning really REALLY fast and it wouldn't stop so i had to turn the power off at the mains? any ideas???

    i did turn the pitch up half turn but i've since reset it.

    the 2 fuses are the same as the 1s i took out, maybe its a problem with the transformer? or the stop/start unit?

    ok well, if the fuses are the same i suggest that you try marking their original position, and the moving them, i would suggest that you play with the pitch resistor also the brake one too... but be sure to mark them so you can reset them acurately.

    let meknow what happens..

    sounds like you have put the wrong rating fuses i the both should be 250ma. Also did you fiddle with the pitch or brake resistors?

    sounds odd, can you explain in more detail? did you have a spillage on it at any point?

No, this has nothing to do with the fuses. The problem lies with one or a combination of faulty IC's (integrated circuits). More than likely IC201 (Turntable Control IC), but IC101 (Turntable Drive) and IC301 (Pitch Control IC) will also cause this sort of issue.

Also take a look at R213, it generally gets very hot, and you can tell by looking at it and seeing discoloration, and might be the starting point to this mess. It's good to replace this as well, while your at it - however, it is no longer available from the manufacturer, so you'll have to match up the rating for it. In addition, take a look at Q2 and Q3 (Regulators), those also tend to burn out at the same time.

Good luck.

This is a common issue with the drive in these units. Unfortunately, there is no easy fix. You will need to take it to a qualified service center for repair.

Technics sl 1210 will not start up


did you ever open the turntable. It sounds like the on/off switch is bad. Remove the platter and screws with a phillips screw driver and just make sure the connections are in place. make sure you disconnect the power first. let me know what happens afterwards.

Technics sl 1210 MK2 does not start


Your switch probably went bad. Does it not respond at all? Does the button at least 'bounce' back when you press it? If not, then you might have messed something up when putting it back together.

1200 platter drag


the platter should have two holes on it,my 1210 does. put your thumb on the spindle and a finger in each hole and prize the platter off. theres no screws holding the platter on just a tapered spindle shaft. it is quite heavy so a good pull will do it. as for the scraping it might be as simple as packaging placed under the platter to secure it for shipping, technics are built really well so i cant imagine it could be anything major. i hope this helps you out, if you need any more help let us know. please also let us know how you get on. darren

bad thrust bearing for the platter. use a penetrating oil on the spindle and let stand. then try rotating it after a while.
