Rectifiers were once made using selenium, and they stunk like hell when they went bad. This may or may not be germane to women.

I remember selenium rectifiers. They had fins to dissipate heat. They replaced vacuum tube diodes and were in turn replaced by modern solid state diodes. That just made me think about nuvistors - tiny vacuum tubes that were replaced by transistors. Some interesting technology came about in transitional periods.

“Rectifiers were once made using selenium”...

Store-bought mushrooms are loaded with Selenium.

There’s no need to nosh on rectifiers...
