Hi Rex:

Yes, although I was hoping for a precision oscillator.  There are crystals at 
1, 10, 50 and 100 MHz each with a trimmer cap.
20 Volts negative ground for power and NPN transistors. So far I haven't 
figured out the ground or the interconnection of all the solder posts.  Maybe 
some type of grounding on the outputs.

Have Fun,

Brooke Clarke
