[R-390] R-390A and the Selenium Rectifier

I'd like to get some wisdom regarding the selenium rectifier used to make
the DC for the relays.
I've got an Imperial (really mostly Teledyne) radio of about 1963 vintage,
and the selenium rectifier seems to be working fine. However, I'm doing a
top to bottom refurb (recap etc) on this radio for a friend and I'm
wondering if this might be a likely failure down the road and would be worth
replacing with a silicon bridge.
If this was an R-390 it would be an easy decision as the copper oxide
rectifier stack is always toast!
thanks,
John
