Hard to find
"I picked up an ampeg 412 speaker cabinet off of Facebook marketplace for $100. Some of the speakers didn't work when I got it but I was able to fix that by just resoldering the points on the PCB. The cabinet was missing two out of three jack. The hardest thing was finding these plastic Jack nuts. I couldn't find them anywhere and was getting ready to give up but then I decided to give mojo tone a shot and they had it. So thank you."
