A suggestion for keeping small parts form vibrating off would be to use just
small drop of blue loctite on the threads of the nut or srcew in question.
Blue Loctite can be easily found in almost any auto parts store.
If you read the back the label it states blue loctite should not be used on
small screws and nuts, yellow being recommended. But... I and my r/c flying
friends have been using the blue stuff for years( yellow is tough to find
anywhere) for years with out having any difficulty removing the nut or bolt at
a later date.
Just a thought when even those items anchored down with the aid of lockwashers
still come loose.

Check the hardware for the tube sockets, and make sure there are no nuts
missing on the underside of the chassis. I repaired a 2K not once, but
twice, due to hardware vibrating off of the tube socket, causing one of the
tube filaments to loose connection. It's been a few years, so I don't recall
which socket it was, but it was enough for one of the tubes to loose
filament voltage.
Maybe when you changed tubes, the socket hardware shifted ever so slightly,
enough to re-establish current flow. After the fan/blower ran awhile, maybe
it moved enough to loose connection once again.
