You could try checking to see if that open has happened where the wire leads connect to the actual winging wire used inside the transformer. Sometimes, corrosion from the rosin used to solder the lead wire to the winging wire will create an open. As you otherwise have nothing to lose with that transformer, cut the outeer wrap of the bobbin open where the leads enter to look for that. But if it smells burnt, that's probably not what took it out. In any event, be sure to replace any caps that might be leaky that would cause the output tube to draw excessive current. You don't want to burn out a replacement.
