[Elecraft] K2 SN# 3522 Build Starting - Question

[Trevor Jacobs]

Hey Don,

Thanks for the reply. That's exactly what I was looking for, i.e. gold
contacts and tinned leads...is there a problem with dis-similar metals,
kind of like a stainless steel screw into aluminum - corrosion over
time. I wouldn't think so, as most IC's have tin leads. Never hurts to
ask though. Anyone have the answer? I wanted to use these for there
reliability. Plan on having this K2 for quite a few years...
