Pull the 84 tube and turn it on. If there is no smoke it is possible that the previous issues caused your power xfrmr to go bad. This often happens when the filter electrolytics in the B+ circuit go bad.
Test the 84 tube also. Although rare, sometimes the tube goes bad due to the above problem.
If tube is good measure the resistance between the two plate pins of the 84 tube socket with the tube removed. Tell us what it is.
