[Elecraft] Re: K2 Condensation?

[Stewart Baker]

I swapped out all of the Elecraft IC sockets for turned pin ones when assembling 
my K2/100. Having had socket problems in my  'day job' the last thing I wanted 
was the same for my hobby.

This thread reminds me that I need to get some more for my up and coming 
transverter build.
