Ladder Filter Blues

Hello everyone!
I've got a simple question ... Has anyone built the diode ladder filter
that is NOT from the '303 - I think it might be the AKS copy?
The reason I ask is because I built it from the schematic from "?'s"
(I don't remember his name) homepage, and I can't seem to get it to
work quite right - namely, the resonance control doesn't make it self-
oscillate, and it isn't very "rezzy" sounding even at high resonance
settings! Anyone know of any mistakes in the schematic? Also, if
anyone knows which filter I speak of, anybody know of a "common"
transistor to use in place of the BC### transistors it calls for?
I just used "garden variety" NPN's (2N3904/2N2222), and figure that
this *might* be the culprit! ANY information is welcome!!!!
thanx in advance -
-Duane
