Snip --> In many cases you can use a volt meter to observe the .2 ac in
the audio stream to the controller rxa in this case taken from tb502-2.
But again be careful when you grab that cas line from tb502-16, there is
110 ac on the next screw terminal. By the way cas goes to 8 volts from
0.2 when carrier is present on the m-pro ep38 power supply.
