The new crystals basically look like most crystals except that inside the large can there is a smaller can. In the small can is the circuit board with surface mount components and the crystal. ICM said that it has laser cut resistors and there are no schematics for the boards and each one may be somewhat different so it is impossible to know what the value of the componenets are.
