KPA100 Receiver Tests failed! - Problem nearly solved (Crimp pin removal)

n0tt1
I don't know if the pins are the same type I have used
and removed, but I used a piece of thin-walled brass
tubing just small enough to clear the plastic connector.
I just push the tubing in over the pins and the "tangs"
on the connector are released.

73,
Charlie,  N0TT

Hi Charlie:

Unfortunately these ate not cylindrical-bodied connectors. So the
thin-wall brass tubing won't work here... too bad, too... that method
works GREAT on many MOLEX-type connectors... I usually salvage old
telescoping transistor radio antennas for that specific use.

Fortunately, all he has to do is to reach in thru the access hole for
each pin and depress the little locking finger and pull the pin out,
then bend the finger back up into position.

73,

Thanks to all who responded, both on and off the reflector.
Tom N0SS and Don W3FPR were right - it's actually very easy to get the
inserts out. The inserts were squeezed together when I was soldering them (i
put them into a "3rd hand" which apparently was clamping down rather
tightly) which caused them not to work anymore. I just had to open up the
contact fingers a bit and no more worries!
Anyhow - problem solved.
I just finalized the testing of the KPA 100 and I'm happy to report all
works FB. Maybe I've adjusted the bias current a bit on the conservative
side, max power out is about 90 watts into a dummy load but the difference
between 90 and 110 watts will never be noticed in practice.

Thanks again for all the good advice I got while building my K2/KSB2/KPA100.
Hope I'll be able to return the favour one day and to maybe work you guys on
the air.
