As i am pretty busy with the restauration of several portable DCC players for the hobby 😃 (i repaired one 130, one 134, two 170 and one 175) i every now and than stumble up to vanished “rubber knobs” (how do you call them) on the bottom of the players. (See photo)  
Are there replacement options available for these Knobs.

Is there also a possibility to decrease the “sticky” effect of the covers and maybe replace the letters on the side, instead of using a donor which doesn’t have the “sticky cover” problem.

Thanks for the reactions in advance.

Hi,  
Feet have been covered in this forum:

Most of them are getting very sticky because of age, with this new grains your player will look like new. Very good quality product for less then $4! (200 pieces) And one dollar shipping cost. Product properties: K0502 + 200 Grains [link for buying](https://www.aliexpress.com/item/4001297404341.html?spm=a2g0s.9042311.0.0.27424c4dFNpWTl)

We have not been able to solve the sticky sides, vs just replacing them.

There are various YT videos of people using solvents, but they wipe out the text as well.

Thanks Ralf. I will check the feets link. 😁Indeed solvents will remove the lettering unfortunately. Maybe there is a possibility to bring them back by using new lettering (printed)after removing the sticky layer.

I came a little bit further with my investigation and maybe i found something that could help us all to remove the sticky layer and place new printed lettering on portable player like the 130/134/170/175. I let you all know what the outcome is when i have tested it myself
