wow, thank you for the very fast responses. I'll double check the greasing (nope, I have to admit I did not pay particular attention when installing, I am THAT naive).
As for the cables, can I just double check which one is the possible culprit? Basically, we are talking of one of three. The ribbon connector and the 2 wire connectors (the 4 pin one does the drawer motor and sensor, the other 6 pin one does the spindle motor, the laser position motor, and the laser position switch). I assume the first one I should be looking at is the 6 pin one, or is it the ribbon connector?

Hi Brentrowemeister said:Fitted the parts mentioned yesterday. Hard to tell at work of much improvement but my dire straits test disc sounds slower with a small amount of improved treble crispness which is usually a good sign.
I have put a few pics in THIS FOLDER
How does it sound now ?
Ricardo
Up to now there is a little more clarity, crisper treble and better bass extension. All little gains over what was already there.
I can't really say anything until the weekend as my player takes a good 3 days to settle to its best.

If it proves worthwile, please report ... I am very interested in this servo psu mod.

The Servo psu mod is a superb improvement, it pushes what the servo clock etc did to a new level.
All I have done this time is improve it further 😉
I swapped 2x 3.2VA tx for 2x 7VA, swapped 4x 16v 220uF Silmics for 16V 470uF ZA and added the extra base plate for more mass.

Hi guys am I the first to try removing the Main processor from the chain and
treating it to its own proprietary power supply. all I can say is WOW!!!!

Hi
Yes it makes a nice change. I run mine off a 30Va tx (shared by motor/laser driver ics) to the standard 5v reg (nothing else runs off this reg).
I had thought of popping the processor and display pcb onto a dedicated small tx and reg. Infact you have me thinking of it again
. Room is an issue though.
What gains did you find, I got better detail and fluidity (less muddled sound).

I have exactly the same situation here but I am still using the stock tx for the motor/laser drivers and main cpu. (Shhhhh, I am still using a sprague 500.000uF 6.3v after the digital reg, and everytime I remove this cap, I loose spatiality and smoothness)
So, isolating the cpu would eliminate any psu line dirt to enter the drivers.
Here I go again

Ricardo
PS:
This is an old pic.... actually I use only the sprague... the NEC caused the fuses to glow at power on so I removed it and the sound is even better now.... so mutch for complicated bypassing in the psu lines.

Hehe - big caps always look uber
Have you measured the cap to see what uF it's at these days?

Digital out transformer
Hi,
Has anyone upgraded the digital out transformer, LT01 ? I saw some advice earlier in the forum to use 76601/3C from Murata or the S22083 from Newava but I didn't see if anyone actually did it and found any gains.
Regards
Pete

Hi Pete
I did think of it in the beguinning, but after the very good mods done inside my CDP, I do not see the point in using external devices to process the signal.

Looked awesome in the workshop! I'm now in the "seen it heard it" club. TY!
I bet it did sound good when you got home! 😀
You saw it before the new tx 😉
Yes the improvements were noticable at home, sadly the work speakers don't do it justice.
