You can start.

The only change as far as I am concerned is already described in Part 1 of the description.
So you should use those revised values in the diff pairs.

There is ONE error in the PCB which you need to rectify first before soldering anything.
But that has also been described, and tried out by Nic.
If in doubt ask Nic, or Alexis.

Alexis promised me again to write the build and test section.
He deserves the chance as far as I am concerned.

Someone asked by PM where to get Kerafol for 2SK1530 / 2SJ201.

As far as I know, only Zhou Fang stocks them.
Anyone knows an alternative source ?

I am currently preparing for testing my first protection board and I am wondering how to handle the molex connectors. Soldering the headers on the board is not an issue at all but I am not sure how to handle the wire side. From all what I have found so far this microblade connector needs a quite expensive crimp tool to connect the wires

Could somebody give me a hint if I am wrong or if there are other/better alternatives?

Markus

Just crimp by hand (long nose pliers).

I haven't looked at this in detail yet, but one might be able to identify the appropriate connector/(cheap !) crimping tool combination here (Don't be shocked, that's a somewhat messy "old style website"):

Crimpen

All, thanks for your hints.
The crimp terminals are really tiny and at the end they have to fit into the connector housing. So I guess the crimp has to be really "nice" otherwise it won´t fit.
But well, I´ll order the terminals and housings and give it a try.
I´ll keep you informed about the outcome
