Solved Atari speech synthesizer IC replacement

[petercasino]

Hello. I'm just repairing an Atari Star Wars sound pcb and have found that the speech synthesizer chip (137308-001) is badly corroded. I'd like to buy a replacement. Is there anywhere that sells these chips or an equivalent?

Thanks

Did you manage to find a replacement? I have some NOS parts if you still need one. Say £10 posted?
