[sdiy] sip opamps?

[Bob Weigel]

I...seem to recall there is a 2068 in sip.  If not I think the 4560 is 
just a little better isn't it noise wise?  The 2068 is used in a lot of 
medium high end inputs like Mackie mixer preamps. I'm trying to recall 
but I'm pretty sure I've dealt with it in sip. -Bob
