Hi;
Thanks for the heads up mike.  My least favorite radio store did a thorough 
search and although they had the tw2 they didn't have the 12 volt wall wart. 
No problem I could run it from the power supply.  You guessed it, the 12 
volt supply was in the box with the tw2.  I'm certain it was a separate 
purchase when I bought the tw1.
