Wouldn't a tube amplifier have a damping factor of one?
Not as a rule. Your formula is correct, but the output impedance is typically not 8 ohms even with highish SETs.
My VTL's range from between 1.3 and 1.7 ohms depending upon triode/tetrode setting giving you a DF between 5 and 6. Similarly, the Audio Research REF75/REF250 amps are around 8.
