Pulled and cleaned more of the tubes. To my suprise, the set has more than likely spent some time in Canada. There were a couple of Rogers branded tubes, one Marconi branded tube, and one Electrohome tube, all with mid-to-late 1950s datecodes.
The transformer on this thing is massive, as are the filter chokes, and they run very, very cool. 25 Hz chokes perhaps? Given the area it was found in it wouldn't be surprising.
