I don't where you got your cart, but if it came with the manual, as it should, it clearly states it's washi paper, it's there for a reason, and it is NOT to be removed as removing it will void warranty.
Lyra Delos 'belly cover'
For a lack of a better description or name the 'U' shaped piece of material? / plastic? on the underside of my Lyra Delos cartridge is starting to fray. This cover is behind the boron whisker cantilever and covers the area where the 4 wires pass from the cart to the tonearm connector interface. So, the question is....I am debating removing this cover because it is starting to drag on my LP's. (other nude cartridges don't utilize the 'belly cover'.) Bad idea? Any thoughts on how to proceed in its removal? Thank You in Advance!!
