I'm going to guess it's some kind of AC power controller, that uses a saturable reactor controlled by vacuum tubes. Or maybe it's a prototype cable TV box from the 1950s

yes it's a vaccum tube power controller, 190-240vac in 220vac out, from the 50's
edit> I removed the big tranny from it, connected the 2 outer coils in series to mains voltade and it makes around 1-2kv on the big coil

These are some large nickel sulfate crystals that I accidently grew over the course of about a week by leaving a concentrated solution of nickel sulfate sitting around while it evaporated. The largest one is about 8mm across.
