Collaro ac544
Hi all, just picked up one of these and it runs, but only if I move the linkage by hand. Seems it is auto stop as there is a lug on the bearing housing under the platter that moves a bar with a roller on its end when the arm moves to the centre of the record. But I can't get the linkage to move the idler arm and switch. There are no levers as far as I can see so think it's supposed to move the linkage via the arm. Any help appreciated. Don't know how to post photos here

Re: Collaro ac544
That linkage operates when you move the tone arm to the right to start the turntable at the end it will auto-stop. That same linkage pulls the idler into contact with the inner turntable rim. You can download the Collaro diagrams for this via a google search. The switch on linkage should be light, otherwise the lightweight plastic tone arm can move on its mount.

Re: Collaro ac544
Thanks Edward, there is obviously something wrong as I have removed the arm and can turn the horizontal arm pivot easily with my finger and thumb but the mechanism doesn't engage the idler or power switch. I also removed the bearing housing from the platter so I can see what's happening and with the idler engaged I can turn the arm pivot as if the arm was moving to the centre it disengages. I did some searching but didn't find anything.

Re: Collaro ac544
A couple of photos of your mechanism top and bottom will let us see what is missing.

Re: Collaro ac544
ok I have moved it that way but no click, maybe I didn't give it enough force?

Re: Collaro ac544
Just see my earlier posts here - do be careful of stress on the arm in the pulling to the right switch on procedure.
