Thanks for the kind words! I had actually planned for a 4 conductor cable but (luckily, given the outcome) someone ordered the wrong cable. It might have been me, but I would never admit it...
That was super informative -- a great video -- and thanks for the shout-out, by the way.😊I never considered the stress of the higher mains voltages of today. Even in Canada and the US the original C64 PSUs were rated for 117V -- the standard is 120V today although it often measures a bit higher in most areas.
Thanks! I am very glad you liked it. I am not sure how much Canada was affected by it, but the history of voltages in the US is quite interesting. If I have understood it correctly, (still need to research a bit closer) already in the 1930s the US agreed on 120V as distribution voltage. This was one of the side effects of the Rural Electrification Act of 1936. But because of the losses in the distribution lines, it was agreed that appliances should be marked with the utilization voltage, which was effectively the lowest acceptable voltage of its designed range, and not the nominal distribution voltage like we are used to, for example here in Europe. So a 117V rated PSU might be fine with 120+V. Check the 9V line under normal C64 load. It should drop close to or below 10V. If it does, the onboard regulators should have a fairly comfortable time.
@@TheLEEC Clearly, you are better versed in North American mains voltage history than I am. Yes, both Canada and the US tend to evolve equally when it comes to such things as these. I have taken it for granted that 117V rated products work flawlessly on 120V, as I have never seen or heard of any issues. Still, I will take a closer look at the C64 9V line under normal load, as you suggest. Again, great video and I look forward to future ones. Oh! I have to say, I must find my own _rocket_ _scientist_ for my own rigorous testing. 😉
I have built a couple of C64 P/S in PC power supply boxes. 9VAC 2A transformer and a 2A 5VDC brick work just great. The DIN connector is still available from several sources. Good video
Interesting. There is the same problem with Tandberg Radios from the 70s. Fortunately it is possible to move the mains lead to the 240 tap on the transformer. Do you know the design of the ribocop? I tried sometime ago too see what circuit was like. The new psu will serve you a long time 🙂
Thanks bwack! I love those tap selectors on old radios. Some tube radios have an insane amount of choices. I suppose they were needed for export products back then. I will get back to you on the RiboCop. So far I have just built it and did not examine the circuit much, but I have considered tweaking the voltage reference to trigger a bit earlier.

I think the power cable with the spiral conduit looks pretty slick, sort of fancy. Great video. I look forward to more.

NASA approved awesome.
Thanks Steve! I know he is still in training, but I still feel inclined to trust his opinion.

The little rocket scientist is the best part!
Secret connections at NASA, I assume...
@@TheLEEC More of a connection to the particular space explorer in the film, really. :)
