Keith,

If your APP connectors do not mate with a bit of a *click*, then they 
are assembled incorrectly.  The blades of the conductors *must* be 
locked over the tips of the spring fingers located in the housing.

Things come in threes so the sayings go, I have repaired 2 KPA100s in 
the last week which did not have the blades of the APP connector fully 
seated - I am waiting on the 3rd one.

73,
Don W3FPR

I don't always get a solid click when inserting into the back of the K3 or into the power supply line. I like the convenience of those type of connectors but they do seem to loosen up over time.
