The message
from raden contains these words:

Electronics doesn't always die with a bang

Nor do they always let the magic blue smoke out even gently.

I used to fix tape modules for Rediffusion, and the commonest
electronics fault was an output transistor that just turned up its toes.
Generally it was mechanical though - grime and wear.
