Just a basic, but relevant point - Dynaco cabinets of that vintage are not sealed.

And, yes, when speakers rely on mechanical vs. soldered connections, they become weak points. AR (et.al.) pots. Dynaco rotary switches. Internal banana connections (yes, they exist). And more.

As a hobbyist with a 40+ year immersion in the hobby, and in a region where all sorts of things are thick on the ground and having lived within 100 miles of a dozen major audio manufacturers, I have seen *lots* of strange stuff. Most recently (May 12th), a Dynaco ST70 and a pair of MkIIIs marked by, and from a Hammond organ. Go figure.
