Thanks for the input guys. Looks like i will go with the inverter to
transformer for the 12vac. Seems to be really the only way. Any idea how
clean the output off the transformer would be? How clean is the output
directly off a power invertor. The 12vac that i need is for an audio
application.

You still haven't answered the question about what you want to run.

If it's for an audio application, it's probably because the device is
producing a bipolar supply inside, for +/-15V op-amp circuits. And it
is probably somewhat sensitive to supply input noise, if it is typical of
typical consumer-grade audio gear.
