Stumbled on your channel. Nice video. Troubleshooting Commodore computers is a great resource on UA-cam. I realize this is a 1.5 year old video but keep up the good work. The C64 stock PSUs are not great as you mentioned. They are filled with epoxy and nearly impossible to fix. It is much better to either find a 1764 REU PSU or a C128 PSU and make a cable adapter or just get a modern replacement. Ray Carlsen makes some excellent PSUs. They don't fail like the c64 bricks do. It is the 5V line that fails, not the 9V AC line as it is pretty reliable, It is unregulated on the 9V side and I don't think it is a cause for concern as it is used for the VIC-II (the 6567 Ceramic chip in yours) and the SID. Your C64 is a relatively early one for the better 1983 board which replaced the very early 1982 boards. It is much more reliable and better video. Since there was likely 10mil of the 64 sold in the USA alone and 17-22 mil in total that is a decently low unit. Some things that help with troubleshooting C64s is a dead test cart and diagnostic cart with harness and an Oscilloscope but you can usually get by without the scope. It is a great time to own a C64.
Wow thanks! Holy crap a year and a half since then? jeez that flew by. And yea i was looking for one of the REU psu but couldnt find one cheapish enough. I built a cheap one to get me by but will eventually get a replacment. I had no idea that there were "better" revisions regarding internals...but i guess makes sense since a lot of consoles and stuff are that way, surprised i have a somewhat low number since im in iowa. Thats the next thing i want to get (besides the SD2IEC) is the diag carts in case i get another one.
