Peter Dahl has 5U4 and 5R4 solid state replacements, too:

The best (and most expensive), however, are the Copper Caps from Ted
Weber. They contain the proper dropping resistors (very important) and
inrush current limiters (also good to have).  Besides, they look sexy:

You can, of course, roll your own.  Here are some instructions contained
within an article about converting a Collins 516F-2 power supply (with
5U4 and 5R4) to solid state:

The octal tube bases are available from:

The diodes and resistors can be easily obtained from Mouser:
