A wall wart with AC output is just a transformer that lowers the voltage. The rest of the power supply, the rectifier and filter, is in the Peavey's chassis.
I have experience with AD and DC wall warts.
What has been said is true- you need an AC wall wart. Of course, pay attention to the other specs, esp. the amperage rating (1000ma is 1 amp.) You can go with a wart that produces MORE than 1000ma, but don't risk trying one that puts out LESS than 1000ma. You should also check the AC input spec- some may be rated at 110 VAC, some at 115, some at 120. If the unit specs say "at 120VAC," a wart that is rated at 16VAC/1000ma at 110VAC may not be up to spec.
If you have time, go to a second hand store- they ALL have a bin of used warts- paw through them till you find what you need. It'll be dirt cheap, as they almost never sell. If you can't find a 16VAC, you might get by with a 14, almost certaintly with a 18VAC, and that small a difference in voltage (either AC or DC) won't harm your unit (or at least, that's been my experience. YMMV.)

Awesome, thanks for al lthe help... it makes sense now and I understand what I am looking for.. thanks all!!!

yes this is right..
if the unit wants a 16 VAC it wants a wallwart that takes 110/120AC to a lower AC value....
I bought a nice joe meek VC3, the guy had the wrong wall wart, it didnt work right, ...and it was a AC to AC,....he had a AC to DC,
anyway, you got it ....

Make sure you get the polarity right on the plug!!
An AC-output adaptor does not have polarity.
