I swear it's that you guys are just famous for the unfoolery and other forums send these plants to rattle your cables. I started out in electronics and hated it, but learned just enough to be dangerous without the electrocution hazard. I work with someone who is a 30 year EE and works with climate extremes/vibration chambers for electronics that go either up to, or even beyond Earth's atmosphere and when I mention this stuff to him messing around even, I get "that" look.
To be honest, having come across these bits of witchcraft is what steered me from internet based, modern audio on my revisit to the hobby. Thankfully, you folks here at AH were believably grounded in consistent, common sense, and I could just forget the nonsense I had been exposed to.
