h1npw: I understand completely about the positioning of the plastic spacers. Do you glue these onto the beocenter itself? - I can't see any evidence (no glue or tape residue) of how they were fixed into place before.
Nothing should be stuck to the beocentre. The frames should be stuck to the glass panel, with the 'locking frame' (the one with the nut) on the left hand side when looking from the front. When you come to install the newly glued glass panel it is dropped offset to the right slightly and then you slide the assembly to the left, which effectivly clamps the assembly down - try locking one of the frame pieces in place before sticking them to see what I mean..
The threaded screw is then inserted underneath on the left hand side and this then locks the whole panel in place.
h1npw: Also I'm missing the small screw you refer to in the left hand spacer and also (I'm presuming) the metal insert that goes into the hole on the bottom part of the Beocenter that the screw threads into. If they're glued into position do you think it will matter if the screw is missing? Out of interest do you know why there's only one screw in only one of the spacers?
I think I have answered that above. A suitable screw and nut will be found at somewhere like Maplin or perhaps a hardware shop, I cannot tell you the length or thread size right now. I have to repeat nothing must be glued to the Beocentre, you may need to access this area in the future!
h1npw: I think I'll opt for the tape to attach the glass to the spacers - do you know if the tape you gave me a link to is the same width as the tape that was originally used?
This is the tape others use and recomend so I cannot see any problems!
h1npw: Sorry to be a pain but I want to get this right! I've been given the Beocenter for free and the only other issue with it is that it's missing it's CD door motor so hopefully I can get it fully sorted very cheaply!
Your not being a pain I think it is safe to say that any question goes here I think people on these forums just want to see these hifis looked after!
I did wonder why someone wanted a motor!
