I'm currently in the process of restoring 2 pair of powered Advents. I'm hopeful someone might have or know where I can get an owners manual as well as a schematic, I know it's a stretch but it would sure help.
I sold these to a friend in the late 70's and when he passed away recently, his daughter discovered them in the basement. I was honored to get them and would love to bring the life back to them they deserve!
If anyone can share anything about these amazing speakers, I'd love to hear.
Thanks in advance!
