My gut feeling is that electrolytics got a lot lot
better in the 70's
compared to earlier generations. It's not just that they're 20 years
newer than the ones from the 50's, they really were better
quality to begin with.
The big changes came in the mid 1950s and 60s, and continued into the
70s. After World War 2, when the military had some time on their hands
and a big pile of statistics concerning component failures, the
industry started to really look at component quality carefully.
Basically, the data from the designs of the 1940s led to a lot of
experimentation and trials in the 1950s, which led to better parts by
the 1960s. The aero industry really pushed things along.
