The part is a TI part from radio shack, the TL082 Dual BiFET OP Amp. The little diagram on the back is identical to the one below for the LM358. I am going to have to make a digikey order anyways, though. So, eventually I will get an LM358. But, for now, I hope the TL082 will work. It's funny, but when you go the the RS site, and look at the TL082, it shows a pic on a National Sem. part instead of the TI part.
HERE is a link to the datasheet.
