Well Paul, if you used alligator clips for the tube connections you could  
change the tube in half the time!

I once built a successful 160-10m amp around a 4CX1000A  with no 
socket at all. OK, it took 10 minutes to change out the tube, but  
you rarely if ever have to replace one.

I ran a single  4CX1000A at legal limit on 144 MHz for years, never 
had any issue at all  with it. These tubes have also been used at 222 
MHz, though one doesn't  see that too often.
