Tubes sure DO have mu - it is listed as a specification on virtually all tubes capable of being used as voltage amplifiers.
Mu is defined as the factor by which the plate voltage changes in proportion to a change in the grid voltage, where all other voltages and the plate current are held constant. Along with transconductance and plate resistance, it is one of the three characteristics that defines a tube's ability to perform as a voltage amplifier:
mu = transconductance x plate resistance
I do agree that amplification factor and mu can be used interchangeably.
