My two B90's are rated at 350 watts
as is a B31 and all are in the low
30's ohm range.  The B30, rated at
300 watts measured maybe 40.

  And since Elektro's are a predecessor to the
Empire line... 

 I had a friend with very good diagnostic
meters and we tested the band heater I used
in an Elektro project.  It was rated 380 watts
but guess what....maybe 150 watts.  What a rip.
I'm sure it would run better at a true 380.

  I have two other Elektro's and the tags read
115 volts and 2.5 amps, or about 280 watts.
We checked the resistance and it measured 28 ohms.   
that is at least 450 watts and it heats like it. 
The calculations/estimats are based on DC formulas,
but close enough for me.

All my other Bs are mid-ish 30s Ohms.  There was one Empire I saw the underneath stamping as 450w - don't recall which one that was but it was on eBay that had a photo of the bottom.  I think this #90 is close to what it was when it came out of the factory.  I been playing with it all night and it hardly breaks the stack steal (I get just a slight bubbling out of it).
