Is my CEC TL0 stopped to work I was kind of suicidal as I do not feel to pay 10K for a new one and I will never find anything the sound as good. A friend of my suggested me to contact Nick Gowan who can fix CEC:

Prior to do it I decided to change the laser myself, it not difficult to do and LT0 is notoriously bad for shipping. So, I get the new TL0 laser assembly for KRELL KAV-250 (they use the same SANYO SF-P1) from Liberty Electronics for $45 and was ready to install the new laser. As I said the spindle was raddling and I was wondering how accurate I can measure the elevation of the CD on the spindle with my micrometer as I have no tools to re-focuses the laser after I replace it. I flipped the LT0 a few time to see how the assemble work all together and then I realized that after I flipped the LT0 the main spindle stopped to wobble. I med the microscopic raddling that I had in the spindle’s bearing is evaporated only because I flipped the spindle and made a few turns of the spindle with spindle upside down.
This is kind of very strange as there is nothing know to me in bearing that would reset the worn of bearing by just flipping the bearing upside down. Anyhow, as I did it the bearing become very firm and very solid with no raddling of any kind. I assemble the transport back and make it to spin a CD. It worked perfectly, with fast tracing engagement and no tracing loosing…
Go figure, it is some kind of mystery. I spoke with a friend of mine who repaired a lot of older German tape machine and he toile me that he have seen them to use self-centric bearings that have a collection of clonuses inside for self-calibrating. I do not know if CEC has such a bearing but the fact it that as I flipped the transport it did fix itself and tight up the bearing. Very interesting…
