Okay! NOW I'm getting confused. I'm NOT educated enough to follow all of
this. I JUST took my FIRST ECE class last quarter and I know how to use
test equipment and I can figure out shematics but that's about it. We only
spent a few weeks on op-amps and only the 741 at that. I'll try and order
some op-amps from Mouser but I'd PREFER to finds them locally. Yes, I'm
replacing the LM301's as per everyone's suggestion on the Sample+Hold module.
If someone could SPECIFICALLY suggest PROPER op-amps to use in place of the
301's as I can't find them OR the LF411's locally, I'd like that. Either
that or tell me the specs to ask the local surplus shop to find a match for
what I need. I don't know even close enough to tell them on my own.
Thanks again, but PLEASE don't send a reply to me AND the list, as I don't
need two copies.
