Re: Question for the designer regard Single-Ended Triode Parallel Feed Line Stage kit

A friend of mine told me the problem of "depletion mode" MOSFET recently. He claimed:

"Depletion Mode will make the quiescent plate voltage of the tube to be much less predictable in mu-stage circuitry. With the simplified depletion mode MOSFET plan, the quiescent plate voltage of the triode is able to vary all over the place."

Therefore, how you address the wild variations from depletion mode FET in both Single-Ended Triode Parallel Feed Line Stage kit and two-terminal current source?
