Generally you have to add resistance to the diodes when doing a selenium replacement as a rule. Only exception seem to be 7" electrostatic sets. You can calculate the proper resistance (or at least ballpark it) by looking up the specs of the selenium in the sams.

But jr_tech is right. You're asking for trouble leaving those bumblebees in there. I'm by no means the last word on TV restoration, but it's been my experience that you can't leave any of that stuff in there and expect the set to work long term.
