Evolution with a vengeance!....

I recall the days when I used to repair television sets, (and radio sets), with their massive cathode-ray tubes, heavy mains transformers, speaker transformers, high voltage generators, various valves, resistors, condensers, coils, etc, all enclosed in a very large wooden box.
The advantage: Every thing was repairable and replaceable!
Nowadays, its all enclosed in a wafer-thin plastic case, and thrown away if something goes wrong with any of the internal magic bits!
I've still got a garden shed full of the old stuff, including boxes of thermionic valves, etc!
Paul....an old-time radio bloke!....
