1949? Motorola 10VT24R, TS-14B chassis

I think that you should really get the rest of the caps replaced before you go any further. Replacing the seleniums with diodes but leaving *any* capacitors un-replaced in a set of this age is doing it backwards IMO.

Be aware that I worked on my TS-14 for sync troubles for a long time and got nowhere! I had replaced the seleniums with 1N4007 diodes and the B+ was too high. I added resistance in line with the diodes and got the B+ where it should be and the sync was fine. Replace the caps in the horizontal oscillator stage. If there are leaky ones the set goes nuts! Other than that, these are reliable sets and have a great picture!

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.
