In my experience, no.  The output voltage varies quite substantially with
the current drain.  My guess is that they don't have any regulation in
them, just transformer plus diodes plus (I hope) a filter capacitor.
This is plenty good enough for their original application -- battery
elimination -- since equipment powered by (non-rechargeable) batteries
has to tolerate wide voltage change as batteries age.

I'd expect that some adapters are better than others, so the definitive
answer is to test your adapter under load:  buy a handful of power
resistors and try it out.  But don't get your hopes too high.
