I think you are right about this too. I have always been stuck on this notion, primarily because the conversion of anode current to a voltage (except for that lost in plate resistance) occurs outside the valve in the load.
Also I have been pretty well stuck on the idea of a transistor as a current amplifier all my life too, though I have a lot less difficulty thinking of them as transconductance devices by programming their base-emitter voltage than I do thinking of a valve as a voltage amplifier. So maybe I'm 3/4 of the way there!
