This is the second project from the RED BOXES part 4 [ the first three parts at the old, nonexisting forum] and it is a 2U rack with four channels of preamps based on jfet amp module [remember those 60 little modules?] and OEP or LUNDAHL input transformers.
Input selector switch is also a gain switch for mic and line and instrument inputs.
