Hello Matt:The impedances and taps are the same as the "regular" TL-404. The only difference is that the XL has 33% larger core.
All of the current 404's are built on c-cores. The originals were built on special (and long ago obsolete) Westinghouse pattern EI stamped lams.

Mike,
So instead of a 2W rating it's 2.6W? What is the application that benefits from that little boost?
Matt
A hair over 3.5 watts - power goes as cross section area squared.

Joe,
I know we are talking about real power now. But given Mike's conservatism the 404 is probably good for real world 3Ws anyway, and the XL is probably good for 4Ws.
I'm building an amp for a college daughter and it's headphones over speakers any day, so one autoformer to rule the world has me thinking. Not sure that I want a big bottle 2A3 out in the open but an E55L spud is nice and stout. I was just curious about the XL demand, and yes I'm american so I know more is always better.
Matt
Three watts! Holy moly! Don't blow anything up!! Wear earplugs!
