good news is, your transformer is fine.
I take it the fuse id not blow with the rest of the tubes in their sockets, with just 84 removed?
Whatever I asked you to do before is no longer needed as you, albeit in a risky manner, tested the transformer and it is fine.
84 needs to be checked for short.
The output of it (across the electrolytics) also needs the short test.
As for the variac, you simply plug your radio in it starting from 0V and see if the voltages behave correctly (like that filament voltage ) as you slowly raise the voltage.

good to know, I did not have a chance to look at them yet.
