Jeff,

Count the number of turns on T5 - it sounds like you may have one too many -
if not spread the turns out as much as possible and see if the voltage
drops.  When counting toroid turns, count the number of times the wire
passes through the center of the core - counting on the outside may lead to
one too many turns (proof is left to the reader <G>).

73,
Don W3FPR
