Hello to group.
Many thanks for the help on my NE612 / NE602 mixer project.
I have completed the shielded  colpitts oscillator module as follows:

72 MHz fundamental crystal from pin 6 to ground
5 pF cap from pin 6 to pin 7
15 pF cap from pin 7 to ground.

Nice clean 72 MHz sine wave on my  'scope,  0.4 V p-p

I'll keep you posted on the progress.
