Schematic link for those following is for a code 121 the poster may have a different build code but this should be close. I'm not surprised the output transformer is cold (they generally run cool) but this one looks dead. Sounds like you may have a good power transformer. Correct me if I'm wrong but from your pictures it appears the rectifier has a rather purple glow. If so, not good. Cease putting power to the radio and pull the rectifier out. You can check the HV windings from the top of the socket with an ohm meter, checking plate 1 to ground and plate 2 to ground. Let us know what you get.
