I have some if you want one, but the thing was an absolute nightmare.
The reissue vactrol never seemed to behave like it should, although I don't know for sure where those were being sourced.
It'll play nice with the vactrol from an original, but those are pretty hard to come by.
I eventually pulled the project because it gave so much trouble, but I suppose I could make it available again with the warning "Build at your own risk"...
