Beogram 4004 Type 5526 - Restoration Project - Initial Assessment and Cleaning

2026 seems to be the year of the Beogram 4004 turntable...restorations that is.

This post begins another nice Beogram 4004 restoration project.  

Here is my assessment.





















































The Beogram is in nice shape and very clean.

The Beo4 remote control pictured next to it is because this Beogram 4004 will be getting a Remote Commander that is paired to the Beo4 controller.

The middle, top of the dust cover has a rather noticeable scratch.  I will try to buff it out so it isn't so prominent later.  This Beogram might end up getting a new dust cover from dksoundparts.




























The keypad looks nice as well as the other turntable deck components.






















































The inside of this Beogram 4004 also looks to be in really great condition.
Of course there is the usual floating debris of disintegrating transport lock plastic material.
Everything else looks great though.




























The tangential arm assembly looks good.






















































I removed all of the transport lock assemblies so I can take out the floating chassis components to work on them.
























The main circuit board and the output/remote control board look good...ready for restoration.













































Here is the cleaned up cabinet and the removed nuts and bolts.




























...and here is the removed floating chassis assembly.  I will start the restoration work with that set of components first.




























I did not include any pictures of the DC platter motor for this Beogram.  That is because this Beogram 4004 will be getting a Beolover Sync Drive platter motor.  

In the next post I will start disassembling, cleaning and lubricating the floating chassis components.
