I know how you feel, I have a white Beomaster 1200, a white Beocord 1200 and white beovox RL35 speakers, looks great 

no turntable sadly 

Oh yes, they looks great! They have that very modern look along with a vintage feeling.
They always remind me the futur's vision in "Logan's run" movie (In which I remember they was indeed a white Beogram installed vertically).

You're lucky to have a White Beomaster 1200. I wish I did. but 1200's where hard to find "complete", always parts missing.
It will have make the set more as intended. But I also like the black panel, matching the Beocord's controls.

As I understand it, the Beovox 1001 are designed for the ambiphonic channels, so I may eventually search for a pair for mains speakers.
I was afraid they gonna sound hollow but I find them quite good and full. But I dont know much about speakers ans even more from this era.

I'll start a specific thread about the Beograms but because I've only one issue with the Bombaster, I dont see the need to log the conversations with new subjects. I Post my question here hoping for someone to see it! 😁

The tuning index is present and complete, but it has a little of lateral play (axial in fact, the axe being the center or the top part) making the tuning difficult and the slider, not sliding well.

I've taken out the bottom part  and I can see 4 screws holding the scale plate. But can the index plate being taken off without removing the tuner cord? Or does it involve removing the tuning wire with the risk of loosing tuning precision?

I think the problem come from the transparent plate having fallen and then glued back but not tight enough. What i want to do is just to pad it with felt to compensate as i believe trying tor remove the glue can risk breaking that important part.

Any thoughts? Thank you.
