Lock screw for Marantz SA 10 And Ruby sacd player

Nonoise I look below it looks like they did not need need lock screw. I bought them open box, Plug and play indeed.i double check their boxes , no lock screw found.

Yes I remember those days you can’t play the player without removing the lock screw.my guess the new ones don’t employ lock screw anymore.

Winoguy17 at present Iam using Audioquest tornado pc and High Fidelity ic, treated with q45 HF enhancer.

Winoguy 17 I checked both SA10 and Ruby, no lock noted. Congratulations for buying the Ruby if you will buy a good pc and ic ? You will be able to get the best performance on your Ruby, truly is a well built and well design sacd player.
