Interesting (wacky!) Tube/Valve receiver

Here's an interesting project: a tube based regenerative receiver that uses an LM386 as an audio amplifier. Wacky. Still, it appears to only use 12v supplies, which may make it a fun and interesting project.

Addendum: Apparently this YouTube video served as inspiration. Cool.
