Ok i bought a copy of airdrawndagger the other day second hand (only copy I could get at the time) and everything seems fine except Magnetic North (side F2).
Roughly 3:25 into the song it screws up and instead of going into that nice ambient breakdown, it goes almost silent. If I crank my speaker right up and stick my ear against the speaker I can make out the tune but only barely. I checked the vinyl and during this whole bit there is a clearly visibile ring which almost looks like what you might see in between two tracks on one side of a vinyl.
I've attached an image to give you an idea of what I mean.
