I always leave the RF deck until the power supply & timebases have been recapped, when recapping the RF deck, the first caps to change are the heater decoupler caps.
These tend to short out and can burn out the valve heaters.
I have never had to change the mica caps in these, just the wax caps & electrolyticS.
See this thread on my set:

As you can see, this set was giving excellent results until the LOPT died.
The set has since had a good replacement LOPT fitted & has been run for many hours without any issues.
