[Elecraft] K2 turned pin sockets

[David Cutter]

I agree with Geoff about turned pin sockets, they are worth the money, but 
they require a lot more insertion force.  Ensure all your pins are straight 
and exactly aligned with the socket before re-inserting or there is a 
distinct danger of folding a pin up under itself and this is sometimes 
difficult to spot.  I've fitted several thousand, I have the scars!
