Poor Universum W2758

[Cyyril]

I'm trying to rescue this vintage flip clock I've bought on E...y ( fool I am ! )
I've removed the cover to show you inside it and repair tiles :


It shares the same shape of Sanyo 6CA T45 with radio AM and FM ( UKW in german) yes all are in German on the shell.

I knew several tiles was away, and clock didn't moves , and when I received it, there was crack on both sides too , the seller wasn't smart with it I think !
Anyway, a few of glue to repair it to forget...



So, here are the tiles again


I managed to repair the broken tiles , Oh my, all of tiles away were broken on a side. What was the life of this clock ? Not very peaceful . So ,trying to Glue with baking soda powder and Glue that I found a tutorial on Flipclockfans video.
The rack of tiles here to dry.

But no success for me, It is too brittle and doesn't stay in the frame
So I decided to glue and very little wire on each tile side and after bending the tile It stays in place ...

More to come...
Bonne journée à tous ( Have a nice day )

Oh man. What a lot of work. Sorry that the tile repair didn't work for you. I'd be interested to see how it works with the wires.

Now, I need to update the volume knob :


the sound is too loud with the volume at minimum , I don't know why?
The nut is tighten to the knob and turns with the knob.
Is it here to adjust ? I'm afraid to brake it...

the component is also loose on the frame ( the black pliers )
I don't how to fasten it ?

Does anyone have a solution?
Thanks a lot.

Here I am:
The motor turns quite good but a bit lazy, need help sometimes.
I've attached all the tiles.
Cleaning all parts.

Here are pictures of my proud Universum !







I've renewed the Brand logo to a custom one with plasticard and decal sheet. The old logo was missing....

I've always a problem with radio. The sound is loud at minimum ....I don't know why ?

Did you clean the potentiometer already? If you did and the volume potentiometer is still allowing sound when set to minimum then it's variable resistance is probably failing. Most likely the carbon traces on the fiber board (circuit board) inside the housing are damaged from age, use, etc. It'll have to be replaced.

You can also remove the wires and also see if the resistance value is marked on the body of the pot itself. Many times they are marked with it. With the wires removed you can attach a multimeter to the posts and move the knob and see if it goes to zero or close to zero at minimum volume. At maximum volume it should be close to the value marked on the pot.

Interesting. Apart from the ear plug jack being on the side and not the back and having both AM and FM band this clock appears to be identical to a Sanyo 6CA-T45AS. Brand engineering? I have seen another example of a Universum flip clock radio being similar to its Sanyo counterpart.

Small tip but it might be handy to somebody somewhere. After I bought this tool I became the Michelangelo of baking soda super glue sculpting
After I posted I read it said 0 available but I"m sure you can find one someplace
