Just wondering if anyone could supply a copy of the 1690 operating instructions manual for this mixer. I've read the tech letter PDF several times
Also wanting opinions and information about it from anyone out there who has used one or remembers much about this model or Altecs from this era. Anything you can tell me about it in terms of quality, reliability, etc? Was this considered a high quality mixer in it's time?

Well, it's a medium priced unit as anything like that is going to be, well made
What are you looking for?
I doubt there are manuals unless somebody finds one, but it's pretty basic...
Late 70's to early 80's
