UX201-A (1925)
Vintage Radio Tube Tragedy ... sort of?
Found one of the tubes in the FADA with a crack in the envelope.
Was preparing my FADA 192A Neutrodyne TRF receiver to power up on
it's 100th anniversary. Got no sound in my head phones. These tubes
don't glow all that brightly in a well lit shop, so, I decided to pull
each one (with the power off, of course).
I was thinking it may be a bad pin connection in the sockets. 1st RF test OK, 2nd RF test OK. Detector RF tube - envelope was in my hand, test FAIL. 1st audio and power out test OK.
I have a few spares, mostly Cunningham. Oh well, replaced the tube and the radio works again.

Put the tube in a honourable position in my display case.
