Beogram 8002 From North Texas: A couple more cabinet repair tasks

As I was repairing the main PCB mounting post I couldn't help noticing the way this Beogram 8002's aluminum deck lid had been reattached. Like many repairs of these aluminum deck lids someone had used a foam type double-sided tape that is better suited for insulation. It is too thick for this application and results in a visible gap at the seam where the aluminum deck meets the Beogram cabinet frame.

I don't like that. Having the gap there would bother me.



































I decided to pull the aluminum panel from the previous repair attempt and remount it correctly.

Here is the panel removed.  You can see the thick double-sided tape as well as the residue from the original B&O tape. All of that needs to be cleaned off and the surface prepared for some better 3M VHB tape.





















































When removing old glue residue I sometimes use paper towels soaked in isopropyl alcohol.  Most of the time though, I just use a product called Goo Gone.  It squirts onto the areas I want cleaned up and I let it soak for a few hours.



























This Beogram 8002 also has a tonearm deck lid that still had the original B&O double-sided tape...now deteriorated.  So I added it to the cleanup mix.



























Hours later I scraped the old adhesive material off all of the Goo Gone soaked surfaces.
That left me with a nice pile of goop.



























The surfaces are clean now and ready for some good 3M VHB double-sided tape.




















































Here is the tape applied to the clean surface of the cabinet.
Note: Don't forget the small spring that fits between the deck and the aluminum lid. That is for removing electrostatic charge on the deck surface.





















































The aluminum deck fits nice and snug on the cabinet now with minimal gap between the cabinet and the aluminum deck material.











































That is how it is supposed to look and is so much better than before.
Last is the reattachment of the two pieces that make up the tonearm compartment deck lid.

Two strips of VHB are applied to the surface of one of the plates, then they are fitted together.














































Finally, here is the tonearm compartment deck lid back in place.
