Before you even go to those coils, and because you did not mention these steps:
1. Check your transformer outputs what it should. For this, remove the rectifier tube (or even all the tubes) and see the High voltage coil end-to-end (will be on 600V level), and the filament voltage (whatever it is that should be there, see your tubes) and the filament voltage for the rectifier tube.
2. Make sure the filter caps are discharged and measure across them, to look for short.
3. Then put all tubes in, including the rectifier and hook up the speaker, and see if there is any high voltage there anywhere at all.
4. If yes and the tubes light up, then see why it is not where it should be (yes, coils open etc).

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
