Quick update.

After many months of endless looking, negotiation, dead ends, etc etc - I have finally secured a supplier of oscillators that will make
custom oscillators with guaranteed, repeatable consistent performance.

In the process we actually upped the spec in a number of areas including the type of crystal used - normally for aerospace applications.
A secondary benefit is this type of crystal has less sensitivity to vibration or 'G' induced jitter.
   
I have the first one being shipped to me now. I also have actual performance plots of this (11.2896MHz) clock - it is nothing short of exceptional in every regard.


Boards being done ATM.

Awesome Terry!  What voltage is required to power the board/chip?   I was hoping can tap the power from somewhere inside me Marantz CD75 SE MK2?

Trying to keep it all packed into the one stock player case, except for the 2 valves sticking out from the valve output stage  8)

WRT, powering from internal, sorry that will not be possible, this puppy pulls huge current.

I will have 2 boards, 1 as per Mr Kajak's which needs 12V DC IP presumably from a battery
The other will be a small transformer /rectifier / caps to supply 12V DC.
You should still be able to fit it in to the standard case.

I am also looking at doing an I2S OP board for CD94 so we can preserve all the 'goodness' of the clock so to speak.
It depends how many people are interested.

Cool!

http://jpegbay.com/gallery/000592941-2.html#2

Quite a lot of space in the cd75, so should be right to fit the necessary bits to power it.  Although only wanting to mod the cd player on-the-cheap, as it is not my primary digital source. Final price for the kit will be the main determinate in my case. 

Thanks mate

Count me in here please, I like the 'front end - back end' approach to de jittering the system.

We all like different things so lets all agree to disagree and if any common ground is found then worship it.  Mine is the KD hence being present on this forum.

Great news about the clocks.  Can't wait to get my hands on 1.

I am also looking at doing an I2S OP board for CD94 so we can preserve all the 'goodness' of the clock so to speak.

T, when you say preserve,  are you adding an output buffer to ensure a strong signal?

Sorry off topic
William,
Try this website for copper sheet
You will need to ring them to see what off cuts are available

What do you want to do with the copper?
2 mm is pretty thick.

cheers

If you melt down the copper from all the hifi you have accumulated over the years you should get 20mm thick top plate chassis ;)

Hi Terry,
Amplifier top plate for chassis

Yeah for amp chassis, I can still use the 2mm but I need to put extra structural supports for the heavy irons on the top, with 4 or 5mm I may not need to do that much.

Thanks for the link Graham.

2.0mm copper plate is very strong - surely that is thick enough. 

Do you have any returns (folds) in it?

Can we see a photo.
