[sdiy] Replacement for CA3160

[Aaron Lanterman]

If one wanted to build a clone of the waveshaper from the Buchla 259, and 
one didn't want to pay $2 for the CA3160's on e-bay, what would be a good 
replacement?

As far as how that circuit works, one of the key phrases from the 
datasheet seems to be:

"A complementary symmetry MOS (CMOS) transistor-pair, capable of swinging 
the output voltage to within 10mV of either supply voltage terminal (at 
very high values of load impedance), is employed as the output circuit."
