RE: Sylvania Gold Pin 12au7WA = 5814?

The 5814 draws a bit more heater current than a 12AU7 - 25 ma. more with 12.6 volts and 50 ma. more at 6.3 volts on the heater. I guess that COULD be why but that would be strange unless there's a bunch of them and the cumulative increase would be a problem.

I've never heard of any case where they wouldn't interchange either. I'd be curious about why myself.
