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?

Thanks! Interesting read.

Wonder what this might do to the 1200uf 450V power caps on my Tube Amp?

All the internal poly caps are strapped down and the plastic mounts they are attached to are attached to the chassis with foam tape.

Another interesting possibility 
Hi.

The rubber was a build up from the belt. Created an uneven weight distribution on the pulley which I suspect unbalanced the pulley causing the motor to vibrate. Because of the motor mount being attached the way it was, this vibration was making its way through to the stylus.
