Any chance you could re-upload the samples? I'm very curious to see if I can detect the differences between the bearings.

I should have the samples around somewhere. Email me. I will say buy a replacement Technics bearing. Fill the well 1/3 with motor cycle chain oil while you wait for a modified replacement. This $60 will get you 97% of the performance.

I would email you, but cannot find a proper contact link from your profile.

I already own two Technics bearings, one with the plastic gear, and one without. Jim at Applied Fidelity suggested that I send the one with the gear. When finances allow, if I can actually hear a difference with some audio samples, I may just do so. The veil and persistent low-frequency noise is starting to bother me.

Seriously pour that much oil straight into the well? That's going to be rough to clean out eventually. I've got the thrust plate wax in there at the moment, which I doubt would play nicely with an oil bath. I wonder what else might work instead, or if it'd just be better to have it suspended in the oil without any further support for the thrust plate. Do you have an audio sample of what that's like as well? I only ever added the recommended few drops of for the spindle. Would more have actually been better?

I may also try the the tweak of removing the plastic cover for the electronics that you recommended elsewhere. It's just such a pain to get my Achromat off of the platter since I bonded them with a thin layer of Vaseline, but it seems like an easy and interesting tweak to try. It's not like my platter rings anymore. :)

Keep the thrust pad in place and fill the well with oil. My current setup is with Jim's bearing.

The next upgrade maybe a machined sealed bearing. However, I've taken the SL1200 as far as I desire.
