I've been picking up old Telefunken solid state modules whenever I can find them for almost free prices on Ebay or the local classified ads. I have picked up some incredbily well constructed and great sounding gear for almost no money. My latest find is a Telefunken ELA E130b, a two channel module that can control the stereo image width of MS or XY signals. At least that's what the writing on the face of the module leads me to believe. Can anyone provide better info on what this thing does and how it works? Or better yet, provide me with a link to any online info? Thanks.
