Installing the K3AUDPROTMDKT ??

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
Fabio

Heat the thru-holes from one side of the board, and use a solder sucker from the opposite side. Wick alone won’t clean these things out very well.

Fabio,

To open the thru-plated holes after you have used solder wick, heat the
solder pads and push out the remaining solder with a wooden toothpick or
a stainless steel needle.

Re: Installing the K3AUDPROTMDKT ??

Thanks guys,
I finally made it. I had to use needles and to heat the pad and the
needle itself. The toothpick was too big to be used (maybe we have big
teeth in Italy?)

Thank you very much for the replies! I was feeling stupid but, hey, I
wanted that mod done!! :)

Ciao,
Fabio

Re: Installing the K3AUDPROTMDKT ??

Fabio,

It is good to hear that you were successful.

Sometimes you have to whittle down the toothpick, but with the thin
"squarish" ones ones they usually work out-of-the box.

I am gald to hear you had success with the SS needle. The only problem
with the metallic needle is that it heats and can burn your fingers if
you do not take precautions.

I use stainless steel needles fashioned from the ground down shafts of
dental tools for that purpose. They are often found at hamfests here in
the US. But then I work mostly on the K2 where that procedure is often
required.
