[sdiy] IC socket question

[groovyshaman at snet.net]

Hey Harry...  I didn't realize turned-pin sockets had less contact force
than dual leaf - always learning, I am.  Oakley kits recommend these types,
so that's the direction I was originally going.  The MilMax ones I've been
considering have gold contacts as you suggest, but tin sleeves.  I was
curious about possible metal interactions.

Now, I've seen on this list that some believe that dual leaf (and especially
single leaf) types are inferior to turned-pin.  But I have also heard that
the Diplomate sockets are better than most, and your comments have confirmed
it.

Thanks -as always- for your input.

Cheers,
George

PS: Doesn't Tyco own AMP?  Hmmm.. maybe that explains getting f'd over. ;)
