The service manual provides a method of setting the reference
oscillator's 5th harmonic to 124.032000 MHz. It was slightly off, so I
adjusted it. However, the original error did not appear to change.

It turns out that the setting of the oscillator didn't "take". I made
the change and pressed the SET button. However the oscillator frequency
had not changed after exiting the ADJUST mode.

Well, it really did take, but only when in the ADJUST mode! There must
be some other way of changing the reference oscillator frequency when in
normal operation, but I can't find it.

There are a couple other oscillator adjustments that don't appear to
relate to the reference frequency. They appear to require access to the
back of the front panel electronics, which is quite a challenge!
