[Elecraft] Installing the K3AUDPROTMDKT ??

[Fabio IZ4AFW / NZ1W]

Hi guys,
   I'm having some tough time installing the K3AUDPROTMDKT assembly on 
the main board of my K3.
As for every upgrade, I am following the instructions. I removed the two 
old electrolytic caps in a few seconds, it was easy and quick.

But installing the new tiny board, as easy as it seems, is just a 
different matter. I was able to remove almost all of the remaining 
solder, but the pass-thru holes just remain closed with some solder. I 
tried with some solder wick but to no avail.
In addition, the pass-thru holes are so small that I don't have any tool 
that I can use to try to open those holes while heating the board with 
my soldering iron.
I tried to align the 4 legs of the assembly but -of course- pushing them 
through the holes is not easy, as they bend as soon as I apply a minimum 
force.

Did anyone of you already perform this upgrade? Any tips for me? :)

Thanks, 73
