Here are a couple of thoughts. How about "Mini Collider" in honor of the LHC's first "wreck"? I really like the idea of building this around a turret board and soldering the tubes vs sockets is fine with me.

It is great to see the momentum behind this idea. I recently completed a Lite IIb with the addition of a VVR. Being ...

Yet another schematic and layout request! Thanks!

Thanks Mark! I've got it. Greatly appreciated.
