DEC G500 Module

We are still fiddling with the TU56 drive on the PDP-12 at the RICM. We
followed the head skew procedure, but it calls for a G500 module to amplify
the signals from the tape head. We cobbled together a pair if G888 modules
as the amplifier, and it worked OK. The G500 schematics are in the skew
procedure so we could make one, but we don't know anything about the
physical layout. Has anyone ever seen a DEC G500 module?
