The MOD102-F is the foreign (Non-USA) version of the MOD 102 including a Hammond 369EX
world power transformer instead of the 269EX. Please note: there is no power cord included with
this kit (due to variations in electrical outlets around the world). You will need to find a power cord
that can fit through the ¼" diameter (6.35 mm) rubber grommet hole on the rear panel.
