Firstly you don't attach drawings to non-binary groups. I haven't a clue what
base 64 would be anyway.


I have a quick question about some op amps. I have included a small sketch
of the circuit in ps/pdf. The circuit is taken from a well known book (it's
rather beginner level so I'm embarrassed to enclose the title)

No, tell.


with the
circuit designed for use with 1/2 of a TL272. I however opted to use a 741

WHY ?

Certain parameters are so wildly different that the likelihood of it working
properly are very small.
