I guess the proof of the pudding is in your observation that the pulley is no longer vibrating. That's the endpoint I didn't see mentioned before now. I suppose you replaced the belt, as well. Better to use a belt that does not deposit a coating on the pulley.
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?
