Google it and you'll get a zillion hits!

Standard 8 pin dual bi-polar op-amp. 3Mhz. compensated.

Almost anything will replace it.

Where are you located?

Well - it is an old part. I found this.

KIA4558S Dual low noise operational amplifier in 9-pin SIP-9 package. Operational temperature range from -40C to 85C.

9 pin sip op amps are not made any more. Ill bet a clever guy could do an op-amp-ectamy with any number of 8 pin dips and make it work. But first, what makes you think its bad? Seriously.
