Purchased a M-80, which was advertised as "mint in the box" (you know how those go) and knowing it would arrive with at least some work needing to be performed, I weighed the cost vs. return and knew what I was getting into. It did arrive with damage from being dropped by FedEx, smashing all the speaker output terminals, however, knowing that at some point I would replace them it wasn't as sorrowful as it sounds. This unit however, does exhibit signs of very low hours usage and all in all, is a very fine candidate for restoration. Since parts will be arriving tomorrow, in the coming days I'll post pics of the project as it progresses this weekend. As it appears, besides the rear terminal replace, this will only require a recap and cleanup.
