A short applied upon the rectifier tube does not usually ruin the tube.

without the danger of blowing out the replaced caps?
This is a small rectifier tube and looks a tad difficult to find and replace.
I don't have the number for it available at this moment. But I'll google it later.

The tube will not ruin new caps, but if the tube is shorted it will damage the power transformer in perhaps 30 seconds if a line fuse is not in place.
I would really need to view the schematic and the tube to make a more accurate statement than the generalization above.
I would power up watching the rectifier tube and shut off immediately with any signs of arcing or other events. It would be best to use a dim bulb tester and a volt meter on the B+.
I'm pretty sure this is the one. I'm at work but it sure looks like it.
I also pretty sure it's the 6x4 tube I'm looking at that glows.
