Hello.
I have a masterclock by LC Audio Technology.
The frequency is 33.8688 MHz, which unfortunately is rarely used in CD player and DAC.
Perhaps the circuit is the same for each frequency and it may be possible
only replace the quartz mounted on board with that as often as I need here.
What do you think about?
Thanks,
Fabio

yes maybe the small caps at the oscillator need a small change.
The schematic of the LCAudio clock was posted on this forum by Lars Clausen himself some time ago.

I spent an afternoon searching through the posts by Lars Clausen but I could not find what interested me.
Among other clock I have is the X03 model, full of
smd into a very small board .I hope that Lars or anyone will reads and send their views.
Thanks again,

Here’s the circuit.... you should be able to replace the xtal without any other change.... make sure you choose the proper xtal:att'n:….

Hello, I'm very grateful.
I could not find anything.
I note that in the circuit you sent me the only value not specified is about quartz.
This may indicates that it is "universal."
Now I have to find a quality quartz ( on the X03 is 5ppm).
I'll let you know when it will mount.
Thanks again.
Fabio.
