tcxo board has the following address:

still need to locate it.
probably just a quick email would sort it out.
I did have links for the exact parts at one stage
The Modded usb3 cards have a good sq effect because it takes the 24mhz clock signal provides it with a far cleaner supply giving it a cleaner waveform
And then it allows a clean external 5v to provide power to the dac although usb cable +5v injection is better again
All mods are judged by ear in a series of a b testing
And then cross referenced at meet ups when there's a bit of an audience
We never did anything with measurements as the end goal was better sound we didn't think using our ears was such a bad idea
not sure what improvement this will add when I already have linear power on my yellowtec puc2....
happy to try though.
These are the links I have found...
