Well, as I was trying to calm myself down, this arrived in the mail. Sony STR-6120. I've been hunting for one and jumped on this non/semi-working unit when it was offered.
It has some sort of gremlin that causes it to blow the output protection fuse. That relegated it to sitting on a shelf for about 40 years. Just as an educated guess, I think it might have something to do with the top cover being installed backwards and cutting off airflow to the outputs. I can hope...
The Mrs. has started to notice how many vintage receivers/amps are in the house (6 as of now). I might have to do some picking and choosing again soon.
