[sdiy] Thoughts on AD823 for a 259-style timbre circuit

[Aaron Lanterman]

I'm hunting for something to use instead of the CA3130s/CA3160s.

It needs to have "rail-to-rail" outputs (notice Buchla starves the op  
amps at with +6 and -6 volts - that circuit depends on the output  
hitting the rails to form a bunch of deadbands).

I ran across the AD823. Any thoughts on it?

Anyone know of a quad version? The 823 is a dual...
