I'm repairing a stereo and it seems an integrated circuit is damaged. I'm trying to replace it, but can't find the circuit in stores. It says (BA6191 345 111).

 

I'm wondering if there's an alternate IC that can be used which can fulfill the same purpose. Perhaps there's another IC with the same specs but another part number?

Call up a stereo service store or individua.. They can probably get the part but may charge a slight premium for orderring it.

It's an old stereo, so I'm wondering if there's another IC with the same specs but a different part number. Also, it would cost a lot to get the part from the manufacturer because they will charge me to import the part from the US and then charge me to ship it internationally. Not to mention the overpricing of the part and the time it will take to import it. So it would be impractical to get it from the service store.
