funny how most people think valves have disappeared. VFDs & magnetrons are valve technology, and both are in widespread use in consumer appliances, and VFDs in cars.

Actually VFDs have bare filaments, and 'heater' usually implies an indirectly heated cathode.
I have one that was 29 years old last May. Still going strong but you can only read the display in the dark. However, everything else is perfect still. It's woken me and the memsahib up for work ever since I got a job that required me to keep fixed hours rather than working when I wanted. I shall retire the clock when I retire. If it fails before then I may consider that a signal I should retire.
