Board Notes for Layout & Design:

George 4/28/08
-----------------------
1)  Add connectors.  Key or make unique for all 4.
2) Put 2 circuits on one board due to smaller size with thru hole.  Currently 2 separate boards.
3) Use right angle connectors.
4) Adjustment pot can be vertical and doesn't have to be rt angle as it is currently.  Board will be mounted differently.

Black and red wires are the outputs.  They got ot proportional valves.
There are 4 pots in series with power supplies.  Not sure exactly what this looks like.  George has schematic.
Brown is connected to relay and resistor.
