Thanks for explaining so clearly. That's a very good suggestion to
have the 1000uF caps next to the output stage.
The rectifier diodes might just as well be there, too, then. All
transformer leads will go there directly (15V - 0 - 15V).
No, directly to the +-22 volt supply, the unregulated one.
I think it makes little difference whether the diodes are
close to the output pair or remote.
"like" changed to "little"

I disagree with this idea. There can be a highish charging followed
by a recovery current spike. These have a lot of energy right in the
middle of the audio band. If would be much better to put this stuff
elsewhere.

Yup, keep PSU currents well away from audio.

I mentioned canceling PSU currents and isolating AC transformer voltages. The energy capacitors belong at the point in the circuit where the largest load takes place, not at some distance location.
