The B+ rail voltage found in tubed circuitry will destroy common ceramic filters. Much of the good sound of tubed tuners is related to the tuned transformer coupling between IF stages.
BTW, FETs are highly oscillation prone, when tuned circuits are present at both the I/P and O/P. That's the fundamental reason for the use of ceramic filters.
