There used to be solid state substitutes for at least some commonly used
tubes. But I doubt if they are around anymore, as there just aren't that
many commonly used vacuum tubes anymore.
You could certainly design your own substitute circuits, but I doubt its
worth it. I seem to recall running acrossa website somewhere that still
sold old vacuum tubes. A google search might be productive if you are
looking for a replacement tube to repair an old junker. best bet (in most
cases) is to send it on to the junk yard and get something more modern.
