Out is 950x and in is OCXO as @b0bb recommended. It is dropped right in on the DIL-14 style without any soldering Q_Q woaaa...rolling clocks Instead of Tubes ? Lol

This clock here is 50PPB (per Billions) ! In contrast of 950X which is 25PPM (per Millions)

Just for the record, Whitigir, is this what you are using? And is it simply a drop in replacement (with due deference to the size difference, for the factory clock? Thanks.

It is what I am using now . However ! It isn’t a simply drop-in. My version of lks004 I was able to modify some parts and make it possible

in order to drop in, you need to have a DIL-14 socket installed like what I showed in the pictures. It also consumes 1A of power, so you need to make sure that your voltage regulator is up to task, if it is, then you also need to modify the capacitors as well. Only some few first batches of lks004 is using these Texas regulators TPS7A4700. Otherwise, you will need to also upgrade those regulators and so on. But doing that much work, you may as well look into Pulsar OCXO which is much better and is ready to drop in if you already have a DIL-14 socket installed

So, for the lower power regulators on the newer 004, it is more likely that you need to look into either Pulsar, or the 575X or the 950X

don't mind the work as long as I have all the part numbers and your pics. [with arrows] pointing @ what part goes where! Great work, good info.

WOW! - great work! No soldering?
Some soldering requires to replace the capacitors and to put in the DIL14 dip socket. You need to make sure that you have the powerful regulator first though. Take pictures of the regulator closeup and we can identify it

Capacitor is here

Clock is here

And wow, mouser us had 5 in stock and today is only 2 lol....

The DIL14 adapter can be found here . Scroll to bottom pace and pick $8.50

The DIL14 socket I am using as picture shown is . It needs modifications by using a soldering iron, push out the pins (heat it up and push it out)

Thanks! When I said soldering I just wondered if the ocxo just pushes into the dip14 socket? I realise the socket itself & caps need to be soldered though - LOL!
I will take close ups WHEN I GET A NEW CAMERA, dropped mine and broke the battery cage cover 'clean off'! It was old anyway (reads ancient!).
Many thanks friend!

You are welcome , and smartphone pictures shall be good enough ? Yeah, if you have the DIP socket, it is dropped in

Also, if you remember, I built my Pinkfaun I2S PC, and I was unable to observe the improvements on LKS004 where as my r2r7 improved to another tier. Upgraded this 100Mhz clock and the LKs004 is now scaling up with my Pinkfaun I2S. It is so awesome!
you've answered the question! before I even ask! I was wondering about the comparison to r2r7 myself actually.
Good work mate.

PS: will take photos of regulator soon enough, my moby does really crap photos too, that is also obsolete! Need up grade moby, but the money isn't going there right now. LOL!

This is a picture of mine. Though I thought I was an early adopter, it looks different than yours.

By the way the picture shows clearly the traces from the top two clock pads (3,4) to the receiving holes for the dip-14 socket. I assume the bottom 2 (1,2) are also connected in some way.
