The most common modification on a 31102 is to swap out the rotary gain switch, add a 31267 line input transformer and change the front panel screening in order to give the module both Mic and Line inputs with the correct front panel indication. At this point, the module is technically identical to a Neve 1084, with the only differences being cosmetic (front panel/knob) design and the incorporation of the BA106 emitter follower board located inside the module. We use the emitter follower in the Line input mod to mimic the actual line input signal flow that the 31102 module has while in use of an 8058/68 desk. It is important to remember that we are discussing the modification of a module with an intent to be used outside of an 8058/68 desk, whether it be in a rack or sidecar."
Check out Justin Weiss' beautiful handiwork on these Neve 31102 modules below and take a close look to see his attention to the smallest details. In addition to the rotary gain switch mod, Justin has also used shrink tubing to wrap the internal wiring to get this as close to the original production pieces as possible.
