Does anyone know what is so special about the RC4559N chip? I just got a price
quote via email from an organ company, and they want $82.22 for one of these 8
pin chips! I'm really hoping that's a typo.

Can't I just replace it with a more common (and much cheaper) low-noise dual

If so, does anyone have a favorite substitute?
