What are you tweaking this weekend?

I reconnected my HD CD-1 a couple weeks ago, as a transport, after maybe 2 years and it plays fine, but a couple days ago I noticed a scratching sound, so I took the cover off (a lot like a chinese puzzle). Directly on top, there’s a metal disc connected to the spindle over a metal plate/shield. This disc is coming into contact with the metal plate but should be ~ 1mm above the metal plate directly below it, but it scrapes on the plate. Probably deeper down it’s now off center, which would likely require a new mechanism

THE GOOD: After applying a little WD-40 under the outer edge I put it back in my system sans cover. I am very, very, shockingly impressed with how much better it sounds without the cover,

Round about tweak

First, when feasible, I take the covers off my gear, as with my Voyager GaN350 and (and my EVS 1200 before it) and my Oppo 105. I also have/had a Marantz HD CD-1, used as a transport. It started making scratching sounds, so I opened it up which included taking the cosmetic side panels off to get the top off (much like a chinese puzzle). Anyway, I was unable to solve the problem, as it needs a complete new drive mechanism ($150 + shipping, so bye bye), BUT, when I put it back in although I didn't fix it, it sounded like a much better transport, stunningly so. YMMV, but if you have a HD CD-1 I highly recommend stripping it down 

On a positive note, I am replacing it with a virtually new Audiolab CDT 6000
