oops, i didn't even notice you replied until now.
lol, sorry about that.
when i wake up later, i'll start working on that for ya.
EDIT: couldn't wait.
#1 and #3 are dual opamps with the most common pinout for such chips, the same pinout as the opamps used on our soundcards. the opamps you should replace them with is a matter of personal preference. burr-brown(now texas instruments) opamps provide a milky, laid back sound, analog devices opamps provide a smooth, warm sound, and national semiconductor opamps provide a tight, responsive sound. keep in mind, there are other manufacturers as well. i suggest doing what i did: purchase a couple(or in my case, a bunch) of different opamps and find which is right for you.
#2 is a differential driver and receiver pair. simply put, this is an opamp for balanced signals. this does not have the same pinout as an opamp and must be replaced with the same type of chip. i can try to find a better chip to replace it with, but i must admit, i have very little experience with balanced signals.
EDIT2: apparently texas instruments holds the patent on
differential driver and receiver pairs, because they are the only ones that manufacture them. the one on the board you have is the little brother(sister?) to the best one you can buy. the only difference between the two is a single digit in the product number, and the "better" chip is the exact same as the one you have as far as i can tell.
