The gain for a cathode biased triode with bypassed cathode resistor and a CCS load is the mu of the tube (assuming ideal (infinite impedance) CCS. If your goal is to eliminate the plate impedance from the gain equation you can implement a half mu stage. It looks like an SRPP with equal cathode resistors and triodes and the output is taken off the lower tubes's plate. Disadvantages are a rather high output impedance and a low PSRR.
