Hello again netlanders.

I have need for a low distortion AF preamp, preferably in a IC
package, that has frequency response up to around 60 Khz.  Power
requirements are low, 100mw or less.  Does this sound like a 
good application for an op amp?  

I have a Tandy semiconductor reference manual,  and on page 43
they have a sample application where a 741 linear op amp
is set up in a configuration with r1 = 1K and r2 = 9K, which
gives a gain of 10 with a 100Khz bandwith.  Am I understanding this
correctly?

Does anyone have any other, hopefully better, ideas on this
subject?

Thanks!
