A house dimmer to a 24VAC transformer at your local home center will work fine for a bow up to around 30" and will be much safer than 120V AC. You'll need one rated for HVAC, not just a doorbell.

One last thing to try if you have a mind to, try slaving another channel to the throttle and plug the esc's into two different channels.
