I would have thought that focussing on one parameter misses the point in that the heater is consuming power to create the electron cloud so V&I combined. But I've never looked at similar/same valves that have different heater voltages 6SN7 vs 12SN7. However some valves can have the heaters in series or parallel. Can't imagine that would make a difference as it's the same power.
