Plans for 2x6 AOF/AUF

[1951oliver88]

A couple years ago I found plans on a real nice 2x6 build that incorporated bot AOF and AUF. It had PVC piping air in as well as dampers that could be regulated from the front. I can not seems to find it again. If anyone can point me in the right direction I would appreciate it.

I dont think you are referencing my build but I did build a 2x6 very similar to what you are describing:
