From the post
I seem to have gotten a bad CA3080 and noticed another poster did as well, so I decided to modify Mark's Janglebox layout to accommodate the cheaper and easier to find LM13700. I have built this and it works, but I moved a few things around. So I'll call this unverified for now but it should be good to go.
