Replacing a non-polarized power plug on my vintage amplifier
I have an old(but very powerful) Technics intergrated amp and the power cord got stripped during a party, it still works but it's a potential hazard to drunk people lol. I want to replace the power cord with something more durable and thicker wire guage, but the receiver has a non-polarized plug which is obsolete. how can I tell which wire is "hot" and "neutral"? I heard that if you hooked up the power wire in opposite of my other polarized audio equipment, you might end up with hum noise and other problems. Any advice would be appreciated.
