Hi Jim
Going back through the archives I see you're about three volts high on
that power rail, certainly more than I 'd expect through normal tolerances.
Three volts though is also a bit lower than I'd normally expect as the
headroom on a series pass transistor, assuming it is a series regulator?, so
would still suggest checking the transistor itself or measuring the voltage
across it.
Loading down the output a bit more would also show whether or not the
output is actually regulated.
