Has anyone here successfully built a Neutron?

I really like the idea of having a Mutron III clone, but when I searched for the Neutron on this site, it seems that everyone was having problems with their's.  Is it an impossible build, or is there a way to build it without any of the issues like the whining?  If not, what would be a suitable replacement if I wanted a really funky envelope filter?

Thanks a lot.

Neutron seems a little difficult for me, but it's still on my build list.
You could make a Nurse Quacky, that's not too hard.
