Hello all, I have this really interesting combo Dist Analyzer/Oscillator unit. Made by 3M (I think) but I don't think many were made. Original acquisition stickers are on top with a cost of $4500. 
The sine wave section works up to the 4th or 5th range, then it gets squirrely. The square wave section is not working. The distortion analyzer worked when I bought it 5 years ago but stopped working at some point (never really used it). The interlocking switches need a good cleaning. Really, the whole thing needs a good cleaning.
All I ask is a donation to diyaudio and actual shipping costs. I won't charge for packing. Sorry for the terrible pics. Dying camera.
Thanks!
