But does anyone want to explain he 9v section at the top right?  Where does that connect?  What part connects?  It just seems by itself.

+9V goes to pin 8 of your op amp and VR in the power section goes to VR on the schem. It's on there, you just have to train your eye to look for it - it can get confusing.

There are a lot of VR spots on there.   :?

I think I am gonna have to hold out til I start etching PCBs before I screw with this on perfboard.

Why not use a perfboard.  The original does.

Just use any TS layout already on line. No need for an etched board. And CD is correct, the Landgraff isn't on PCB either. If I remember correctly, the LED's and diodes aren't even on the board. They're just covered with heat shrink and wired off-board.
