Krell SACD Standard: grinding CDs prob.solved


Hi
By pure accident i solved the problem of notoriously noisy transport on Krell SACD Standard.I needed to replace a fuse (switching from Hi-Fi Tuning back to stock)and misplaced the original Krell fuse which was labeled as slow blow 500 mA.Without having one on hand i installed 1 A slow blow fuse and that resolved the problem.The unit runs barely warm (compared to hot with 0.5A fuse inside) and all the noisy CDs are spinning dead quiet now.
I have 2 possible causes for this:
1.because the unit runs a lot cooler now,it prevents some part inside which previously caused the grinding noise ,
from getting expanded because of the heat.
2.because of urestricted current,the whole mechanism is not strainig and operates as it suppose to
Note:the fuse inside my brand new unit was 500 mA,installed at the factory.When i called the tech.dept. to inquire about the fuse,they said the fuse inside according to the technical papers should be 0,8 A.I don't know if it is a quality control issue or what,i am glad the unit is spinning disc and is silent.Too bad i strained thru the grinding noise for the past 3 years.

My Krell Sacd player stop reading and playing disc more than a year ago. Always had a loud transport but loved the sound. took it out yesterday, unpacked it and gave it another try. Same thing. Would not read the disc and tray would open after a minute or so. With nothing to loose, I took the top plate off and used a different fuse. Makes no sense to me, but has worked great ever since, and more quiet than ever. Been using the Showcase Dvd up until the change and it does sound better. Whats going on?
