[Elecraft] KPA100 Receiver Tests failed! - Problem nearly solved

[ON4WIX]

OK, I goofed once again.

It turns out that the advice to NEVER work on the kit when you're tired or 
not thinking clear is a piece of GOLDEN advice.
My KPA100 was nearly ready on Friday night, I only had to attach the cables 
to connect the KPA to the K2 motherboard.
Instead of waiting until Saturday morning I decided to continue working 
until this was finished, even though I was rather tired. I should have known 
better.
I have now found out that I inserted the crimp pins the wrong way into the 
connector bodies, so P6 (aux RF) was not connected physically to the antenna 
connector of the KPA100! No wonder why there was no reception...
Anyway, I'm now looking at the nice job to try and retract the crimp pins 
from the connector housings. They seem to be lodged rather tightly.
If anyone could give me a hint as to how to get the crimp pins back out of 
the connector housings without damaging the parts I would be very 
grateful... BTW, are these connectors standard items so I could get 
replacements easily in case I damage the connectors?
