If that's the case Steve, I would only be concerned if the amp's firmware 
reported a fault due to high line voltage and perhaps causes the amp to 
trip-out.  Because of filament voltage, I'm much more concerned about line 
voltage with my tube amps and really have no concern when using my SPE. 
Line voltage here typically runs 252-255VAC.
