Finally managed to get my setup running, but found out that i got a (potential) major problem I noticed that my turntable, a Technics SLQ-200, does not come with a grounding wire. I know this is an easy fix because all i need to do is buy a new wire. However, when i look up to my amp (an old Kenwood KA-3004) to my horror is that i can't find the screw where you usually hook the wire to. All i can find is a hole and i assume that this means that the screw is missing, so my question is.. Is the screw replaceable, and even if it is, will it be specific to a particular model or any screw can do? Or is there a way where i can just attach my ground wire without a screw. pics below to show you all some details of the missing grounding screw, sorry for the low quality pics, apparently my phone has a problem with its camera causing annoying purple tint luckily, the amp is functioning well aside from the awful static caused by not using the ground wire

Regretting that i choose to wait and not to pick up the clear when it's available. Will the clear variant be available as distributed titles? Planning to get this release with the Infinity repressing.
