[ARC5] BC-454-B Power

[MICHAEL ST ANGELO]

Robert Downs brings up a good point. Historians always caution us that one should examine why something was done not with a present day frame of reference but with the reference and the conditions at the time when the action was performed.

This discussion of surplus conversion is an ongoing topic on this group. I wish more people would operate than spend time regurgitating this topic. No wonder the bands are quiet.

At the end of WW-II and for several years thereafter Jeeps and almost all civilian vehicles still had 6 Volt electrical systems.  And when the progressively heavier electrical load caused the car companies to increase the electrical system voltage in the cars and light trucks they built, they unfortunately went from 6V to 12V instead of to 24V.  And have unfortunately been stuck there ever since.  But that is another subject.

The Silicon diode didn’t start to become commonly available until around 1960, about the same time that the short shelf and service life of the Selenium rectifiers began to become apparent.  So building a cheap LVDC supply wasn’t an option.  At least not for most people,
