You can get very large gain from a CCS-ed pentode. And low output Z thanks to the mu-output. Tune the gain with a resistor between plate and ground. Gary Pimm is the first I heard writing of this, and unfortunately I have not spoken to him in forever.
CCS tuned for the idle current and the resistor current.
