What is the aux DC output on the quad 33 rated at and what was it

headphone amp...

I'd say probably to switch a relay which handled the mains on a high
powered amp - the switched mains outlet from the 33 is pretty weedy.

mmm... good idea - I hadn't thought of that! It doesn't do anything in
the 303 though, so they may have been thinking of more power at some time.
It's only half-wave rectified, which makes sense for a relay.

Well, Quad stuff was often used (modified or altered) for pro work, and I
seem to remember reading that was what it was provided for.

Yes, and IIRC only 100 µF of smoothing - so not designed for much in the
way of 'audio use' current.
