Mike, You referenced this post from Dec 2000 about a 160 volt CS generator:

It implies that the high voltage transistor is used to drop the extra voltage when the system current approaches the 1ma level at which time the maximum voltage would be across the LM334 instead of across the CS cell. (Acting as a variable resistor.) Dan >>Does anyone have a drawing or description of the part of the circuit encompassing the high voltage transistor and resistors which are used for dropping the voltage down to the allowable level for the LM334? > >Won't help, Dan.
