Lyra Skala

That skala has the paper missing from the bottom. It may or may not be operating properly anymore and certainly the warranty is voided Demo or not. In the manual for all Lyra it says explicitly to not remove the paper (like a rice paper) from the underside.

The 'paper' is a dirt guard, to keep dirt, dust and grime from getting up into the coils.

I also thought the "paper" served to reduce any reflective "feedback" from the record surface as well?
I have had the Delos and now have a Kleos and without breaking out the manual or my research, I swear that I read somewhere that the "paper" serves a dual purpose.
So if the Skala in question has the paper missing, then I would think it may not only have a potential of some damage but also a different sound. Just my opinion of course.
Maybe Mr Carr can verify this.
