[sdiy] LM13600 substitute for diode ladder

[Harry Bissell Jr]

I'd suspect that either one will work OK...
I don't have the schematic in front of me.

The difference would be slight, if anything.  The 
buffer amplifiers are slightly different, but that
would only affect the possibility of voltage
controlled
resonance CV feedthru. Not a likely problem in either
case... if you have some CV fast enough to break
through, it will drive the filter (and you) nuts long
before that...
