While more and more asked for a version with the LDO, taking the 5V from the diode, I did a livestream from the microscope cam. It´s uncut and nothing was prepared.

Now to the Video:
Step - by - step - howto - modify the AnalogDevices AdalmPluto with a TCXO on a extra PCB.
The video is done to show step by step how a modification can be done. It´s not made to show you "in perfection" my skills, NO, it´s done to take away your uncertainty and I´m doing the steps extra slowly, shacky, imperfect to show you: YOU can do that, TOO! If I would do it like my mods are done, and I´m a perfectionist, it would scare you from trying it. So yes, this video is to show, it could be done with "not so good" skills. Believe in what you do!
More info about this method:
This method is not perfect cause the noise on the C165 Voltage isn´t small.
For a first usage or if your standard isn´t ultra, it´s fine but
if you want/need a perfect signal, you must add a low noise regulator!
Not all Plutos are equal. I did some like you see in the video and they sound great, but others (most) don´t. Mostly they sound a little sqirly and gourgling, then you must really add a LDO. Look what your local store has available with low noise and the right voltage for your (VC)TCXO. Adding extra C helps also. You can take the 5V for the LDO from the "other" side of the big diode, thats the easiest access to the 5V from the USB,
If in the comments you aks for the "perfect" version, I can do one and hopefully Piero can edit it. I´m not good in editing, so again here, special thanks to Piero for his superb work. Your comments make the difference.
My GND mod, published first on twitter, is done to stop disconnecting the USB or LAN Adapter. So if you wanna use it via LAN/Network, this is the easiest way to fix the disconnects!
