My Fisher stereo stuff still has in it the same capacitors and final drive
tubes it had when I bought it, used, in 1970.  I did replace the pre-amp
tubes with low-noise "milspec" items in the early seventies, but, other than
that and a repair to the tuner's case, it's all original.

The oldest working computer around here is a 1983 Compaq Portable II, which
still has its original power supply.  Early CPQ power supplies were not
known for robustness, but this one has lasted well.

When I was rehabilitating old computers for a charitable organization in
California, we had a couple of machines go "BANG" when we powered 'em up.
It lent extra excitement to the process of rebuilding the machines.
