In the two columns below are pictures of my two A84s.
Both worked & sounded great for a few years, until 2013, when one started squealing,
and the other developed a huge "leaky" capacitor, I mean literally leaking and dripping oil.
I just retired, and I think later this year (2022) I'll finally restore both, and post some "after" pictures.
