I'm just curious. You say the pulley was coated with rubber. Does the rubber represent wear on the (presumably) rubber belt, or is the rubber coating part of the original build of the pulley itself? If the latter, what did you do to the rubber coating in the course of fixing the problem? Because I don't see how anything you did would directly address the problem "vibrating pulley". The measures you took would tend to counteract the problem but not directly fix it; the pulley should not be vibrating, obviously. Thx.
Clearaudio Concept Tear Down
Had a moment last night, and decided to take my Concept apart. Thankfully, curiosity didn’t kill this Jazz Cat...
This was spurred on because of a noise coming from the motor. That, and when I started looking into the noise, I noticed the pully was vibrating. Not good.
Pulled it all apart, removed the motor and cleaned the pully which had a coating of rubber. Suspect that was part of the vibration problem. I also added some damping in all the motor mounts in the form of electrical tape.
When reassembling, I made sure to tighten everything down properly, including the diy spiked feet I made for it. Noise and vibration from motor were gone!
Was quite surprised and the improvement when I had it up and running again. Better dynamics, clearer highs and a more transparent mid.
Super pleased, and quite frankly surprised at the improvement.
Any others have experiences like this?
