NF-1720 Colpitts Crystal Oscillator

There are two versions of this kit. If you have an "R6" Resistor on the PCB, then use Schematic-Rev A. If not, then use Schematic-Rev B. Rev B is an updated version and both circuits will work the same. Rev B is a new PCB layout.

The pictures below are of Rev A.
