at a thrift store. It's complete, and in great shape and seems like it was nearly not used since it was built. The inside of it is immaculately clean with no dirt or anything. I inspected it a bit, and turned it on... and then
I did some serious searching and found the service manual
(which seems to be for the 1b, this is the 1a), and this post
that mentioned a semi-similar issue.
I guess what i was hoping was that there was someone on here who had experience with these, or remembered owning/working on one back when they were current tech. I figured if anyone who knew anything about these was hiding out but still active online, MeFi would be a good place to start.
So yea, basically, any thoughts on this? I have a lot of experience working on modern
desktops/laptops, soldering(including stuff like recapping amps and modern desktop motherboards), and building stuff like tube amp kits. I also have the assistance of a really
experienced technician who remembers this thing from right when it came out. He never worked on these, but is game to help me.
