I’d recommend watching some videos from GR Research first. I don’t know anything about your background, but know that GR Research has some reasons that they don’t sell a power cable DIY kit and instead choose to assemble them in house for sale. I believe it’s a safety related issue if a power cords gets wired incorrectly. Just make sure you know what you’re doing. It seems like it’s similar to some work on tube amplifiers that have extremely high voltage and can be very dangerous.
My First DIY Power Cable
Thinking of trying my first DIY power cable. Would like to keep it under couple hundred $$. Looks like it could be done with products from the Furutech site. Any other resource recommendations?
