Basically the resistor will smoke if its right end is connected to high voltage.
Of course check the wiring and the panel.
Here's how I would do that:
1. Power OFF, radio is UNPLUGGED !!!!
2. Measure across the cap #58. See if there is a suspiciously low resistance.
3. If not, Check the cap for reversal.
4. If yes, trace the short.
PS. FOr a time being forget about the tube, the path is also protected by the anode resistor, so first do that above, then we will think of other venues.
