put finger to keyboard and composed:

However, that then doesn't stack up with the
secondary side voltages being steady, but wrong, and worse than wrong,
unbalanced.

As has already been mentioned, there could be something wrong with the
OP's measurements. He states that "currently it is outputting +17 on
one output and somewhere between +22 and +30 on the other output."

One would expect that the +/-15V supplies would have identical
windings. Moreover, since they would be wound over the same core, then
one would expect that the two outputs should track each other
reasonably well, allowing for slight load differences.

Maybe there is a clue in the fact that the OP's measurements are both
positive. Could it be that he is uing the wrong 0V reference?

For example, if he is mistakenly using the -15V rail as the 0V
reference, then he would be measuring +15V for ground, and +30V for
the +15V rail, if the supply were working correctly.
