 Bob, =20

 Thanks for the info.  A JFET might even work to test the theory.
 Do you happen to know the part number for a JFET that is included in
the Spice program?
 I haven't chosen a specific FET or a particular vendor yet, so their
models are viable at this point.
 However, if I can't find one within the program, I may have to go that
route.

Thanks and Regards,

Jim
