Leonard: Fantastic job.
One little nit: in the graphic illustrating the tests for the OpAmps (as well as subsequent graphics), you refer to "JP2 Tip" and "JP2 Ring". I believe JO2 is the jumper for switching the Xtals; the kit (at least mine) did not come with a header pin strip for the ring/tip/gnd pads. Tx es 73 de Robby WB5RVZ
