The 'lytic cap towards the front of the chassis urped out its guts at one time leaving the white borax deposits, probably shorted. At any rate something shorted and took out the xfrmr, or the xfrmr commited suicide.

A new power transformer would be a horizontal mount like the old one, with 120 volt primary winding and the following secondary windings: 5 V @ 2 amps for the rectifier filament, 6.3 V @ 2.5 amps for the five other tube heaters, 250-300 volts center tapped (CT)@ 70 or greater ma. for the high voltage. Antique Electronic Supply has a sale on new Hammond xfrmrs., or Playthings of the Past may have a used one that would fit. A new one is going to run $50 or a bit less. Then new capacitors to replace the paper ones in the set and new electrolytics to mount under the chassis (leaving the old tall cans up top but disconnected, for looks) might be about $12 or so. There could be some bad resistors (check them with ohmmeter) but they are cheap if needed, fraction of a dollar. New line cord (Wally*World has nice ones 8 ft. long with molded plug.)

A few other tests before getting into it: continuity test with ohmmeter on audio output transformer, speaker voice coil, speaker field coil, RF coils, IF transformers. Make sure everything has continuity and registers at least a few ohms, nothing's open.

Thanks, you make it so simple. In words I know it is, but my mine is telling me oh god this seems difficult I know in all reality the hardest thing is finding the transformer. I am just concerned about connecting the wrong lead to the wrong area. I am keeping an eye out for a parts console on the bay with the same chassis figured that would be the easiest option for my mind to handle.
