Polarity of the power cord

[Mnyb]

Kudos to mr Bill Whitlock for prominently pointing a finger at unsafe practices re electricity lifting ground etc .
Whatever you do to fix your hum issues don't kill yourself .

Who has not in the past operated and old fashioned oscilloscope with cut gnd wires only touching the plastic knobs and not the chassi thankyou battery operated scope meters ...

Another Bill Whitlock (Jensen Transformers, retired) seminar paper:

An Overview of Audio System Grounding & Interfacing

Really hard to read these PowerPoint presentations ... time consuming...

The next question occurs:
Assumed, the amplifier does best at 1V, and reverted plug 10 V to ground.
All other devices are around 1 V to 0.1 Volt, rsp.
Should these items be polarized to have the higher voltage to reduce compensation current via RCA ground?

If someone hasn't already mentioned it, maybe this will help.
