There's slots for three input modules (A,B,C), and 10 output modules
(1-10), and they're all optional and easily reconfigurable.
Just to be clear, the modules themselves aren't reconfigurable, but the
mainframe is.
That said, the 1 MHz, 5 MHz and 10 MHz output amps share the same
circuit topology and board layout (although IIRC the actual boards are
marked distinctly.). It is easy to convert a 5MHz output amp to 10MHz
and vice versa by changing a couple off-the-shelf Cs. The 1MHz output
amp has a different transformer in addition to several other parts. The
transformers are HP specials with unspecified characteristics.
