Yes, and AC output wall wart should provide the needed
voltages. However, we don't know if the application would
work just fine. How many watts of 24 VAC do you have, and
how many watts of 110 VAC do you need?

Should be able to convert 24 VC to 110 VAC. You won't have
much amperage to use, on the 110 VAC side.

Suppose I have a plug-in transformer that reduces 120VAC
power to some
lower AC voltage (say 12VAC or 24VAC), and suppose I want to
do the
reverse---increase a low-voltage source back up to 120VAC.

Would there be a problem in connecting the low-voltage power
to the
plug-in prongs of the wall wart (instead of the normal use:
plugging the
prongs into the wall outlet) and expecting to get
high-voltage power
back out the other end?

I guess my question is answered if I know that there are no
components
other than the transformer inside the wall wart.

My immediate need is to use a 24VCT (center-tapped, 3-wire,
12VAC or
24VAC) to convert 24VAC back up to 120VAC.
