Central Transformer Co. transformer. Hermetically sealed. Four 1/4" corner studs and terminals on bottom.  117V AC 60Hz primary and miltiple secondaries.  Four 6.3V outputs at 1.5 amp, 3 amp, and 6 amp.  One 225V AC output at 25 milliamps, and One 400V AC at 120 milliamps.  In the olden days, transformers commonly specified output voltage in DC assuming the user would be adding full bridge rectifiers. So the 400V DC @ 120mA would be the final output capability of this transformer.  AC output at the coil of the transformer will be slightly more.
