I've posted this in old stylus thread discussion of mine but thought it may be best to open a new thread. Can you please help and tell me whether this is a unequivocal sign of the time has come for my old stylus (still the one that came with my used record player three years ago): A record was playing and at some point I heard this familiar "pop", a hard and isolated one, not the "frying bacon" sort of surface noise. I've had heard it before, that song, on that same spot. Yet this time, it "popped" twice (one in each turn) and then on the third the arm slides all the way to the centre, with stylus on record surface, after which the arm lifted and reverted to initial position. Took the record out, made a visual inspection, and spotted the a small smudge in the track in question. Went for my liquid (10% isopropyl alcohol in distilled water) and cleaning baby brush, cleaned carefully the whole record, and upon another visual inspection the smudge was gone. Waited for the whole thing do dry up (took the opportunity and carefully cleaned the stylus with a small portion of the same mixture sprayed on a dedicated stylus brush). Here's what happened next: record spinning, placed the stylus at the beginning of the track, lowered the arm and... the whole thing happened again: arm slides all the way to the centre, with stylus on record surface, arm lifted and reverted to initial position. Diagnose please?!
