The turntable at present is sitting in its cabinet, so tomorrow I'm going to take it out and sit it on the table where I can work on it properly. Haven't really delved into these things before so am unfamiliar with the components - but, willing to give it a shot. I have a copy of the service manual but it's very poor quality. If you could give me an image of the component I need to work on rather than a name that would be great, or I could post some images and give you a better idae of what's going on. Are we allowed to post images in this forum?
I have lots of oil in the garage but the finest I can think of is for my air-staple gun - a very light machine oil I think but I can purchase whatever you think might be best.
The light source - if you're talking about the light at the end of the sensor arm - is incandescent and plainly visible when the turntable is on. Where's the perspex ruler?
Thanks again, could take a while this as I'm nine hours ahead of you but really want to get it sorted.
