It's an interesting question: you get things like the EL41 and UL41 which you'd _think_ were the same innards with different heater-voltages, but the published figures don't necessarily bear this out.

There are also oddities - I've seen a version of the 6V6 with a 300mA heater rather than the usual 450mA - it was apparently used in some US TV sets.
