Eric, good that your 100w light does not light with the 84 tube. As Mike said, a variac is also very handy but the light will tell you a bit about current draw.
A long post, I would check your two e-caps to make certain the are wired correctly. Item 61 the 12mfd should have it's negative going to the center tap of the high voltage secondary on the power transformer. Item 58, the 16mfd should go to chassis.
Set off, take a resistance measurement from the cathode of the rectifier (+ of the 12mfd) to ground. Negative lead on your meter to ground. Give it a minute to stabilize and report back.
Seems something is putting a load on the power transformer, hence blowing the fuse. The 1 amp fuse should provide enough overhead for the 60 watt radio even on start up which will be a bit higher.
Let us hear back on your resistance measurement and cap checking.
