A DIY Tube Microphone.... and yes, it's a KIT! What's even more awesome about this is the microphone body, grille and other stuff is included in the KIT. Anybody that's into building DIY microphones know this is the most hardest thing to DIY... the microphone case. Not the electronics, not the power supply but the mechanical enclosure! So this kit packages everything nicely.

I bought this kit on eBay and sure hope to find the time to build it. I'll post pictures of my build.
