We have two of these Audix Stereo Width modules. The listed price is for ONE unit. The labels are faded too much to read the module number. They appear to be intact other than the carnhill transformer has been removed. They each have 5 inductors and a sowter 4335 output tranny. The only controls are a bypass switch and a single width control pot. I suspect this is a rudimentary ms box....but then again, maybe not..
