Can anyone confirm that the "new" switcher adapter that arcadeshop is selling for MCR games has eliminated the dreaded audio hum side effect?

I am on the fence about ordering one of these for my TRON.
 
i had a hum through mine as well as some crackling in the speakers, and that's cause the +12 on the switcher was too high, so i put a 12 volt regulator in line between the adapter board and the switcher and that fixed it.
