Any recommendations for a (4W SET amp) power cord. I am looking to buy a power cord and would like some input. Thanks
Here's a good start.https://global.rakuten.com/en/store/chuya-online/item/92479/
.........................................................................Manufacturers do not know my needs and do not know the electrical installation of my house, it has no grounding, so the 3th grounding wire is a waste of wire and could be used as input wire force.
Most condos and homes have a ground but it dont works, due oxidation etc so I use a virtual ground I made.
$95 for 6 feet of braided power cord is a pretty good deal
Is it? Lots of 12g stranded copper wire is way under $1/ft. You can get mil-spec sliver-plated wire with teflon insulation for $.60/ft from Apex Jr. $.60 x 3 = $1.80/ft x 1.2 for braiding losses = $2.16 x 6 = $12.96 + about 5 minutes to braid it. This makes excellent budget power cable and is what I'd personally recommend, except use 2 runs for ground and a 4-strand braid.
Are you recommending that for a 4 watt amp? Or just a general recommendation? I have a Bottlehead Seductor which is 4 watts.
All manufactures are required to follow the rules about Safety Ground/Protective Earth connections.If your area has NEC type rules, you should add a GFCI wall receptacle. While it doen't add ground fault protection it does add human protection.a virtual ground will NEVER act as a Safety Ground/Protective Earth!
One can purchase power cords designed for use in data / network centers for low dollars. They are usually 14GA/3 with double shielding. Designed to carry lots of power and to reject the high levels of EMI present in such centers. These are commonplace cables and can usually be purchased for $12-$15 each. Just make sure to get a cable with NEMA 5-15 and IEC32013 connectors.
a virtual ground will NEVER act as a Safety Ground/Protective Earth!A house in a wet area with a new 10mm dia. 3M long copper bar insert on the ground will work fine(resistance under 2 ohms) about 6 months, after 2 years(2 winters) the copper bar will be correded and resistance increase to 5 to 10 ohms and its not operational anymore as a electrical ground.These electrical rules you mention are valid only to US that use a low tension 120V to homes.
