MD / Genesis Power Adapter (PSU) - voltage readings

[MtothaJ]

On my 10V 1.2A PSU with a multimeter I am reading 14.22V (reading taken not under load) - seems quite high
Can you let me know what you are getting on yours?

That's normal. Since the original power supply is a linear unregulated power supply it will always be at it is higest rate under no load. When you plug it in and turn on your megadrive / genesis it will drop to 12V. If it out putting 32V then it is broken (Actually happend to my power supply)

^ this. No need to worry.

I have couple of problems as I as of yet still do not have access to create new posts. I will start with the first issue that I have. Lately, I have experiences the infamous explosion on my Sega Model 1 Power Supply Adapter. I forgot to take it off, it got overheated when I was sleeping only to find out that it short circuited. Tried to open it up but I couldn't only to realize that it has priority screws to which I have been looking all over the place for them but there was no way of me finding any. That is when I decided to take matters into my own hands. I went to a hardware store and got myself a power supply that is 9v with 2a. I plugged that into my Model 1 Sega Genesis and it worked however this is when things started to get weird. When I was playing, I took notice that there was a lot of flickering on the screen. So I started to do some digging around here and most have mentioned that it was time to replace the capacitors of my Model 1 Sega Genesis as they due tend to wear out over time. That is when I got myself some new capacitors and they are the following, 5 pieces of 220uf 25V, 10 pieces 10uf 35V, 8 pieces 47uf 25V, 6 pieces 1uf 50V, and 9 pieces 100uf 16. The guide that I used to solder in these caps are from here. https://console5.com/wiki/Genesis#IC_BD_M5_USA_VA3 Also before I started to replace all the caps, I took notice that some of the caps on that guide says for example 10uf 16. The hardware store that I went to doesn't have that but he suggested that I would use a 10uf 35V since it will still work and will keep things on the safe side without it reaching the limit. Now after soldering in everything including changing the two Voltage Regulator to 7805 5V (printed text on regulator *L7805CV CCDKJ V6. After putting in everything back together and turning on the console the console works! Which is great! However, the add-on that I have The Mega Disk (Game Copier Floppy disks) no longer functions properly. It used too and I was able to use it all the time 3 days ago before replacing the caps and undergoing this project. It powers On however, when inserted the floppy everything just freezes. Turning the console Off and On again, no menu shows up. There is nothing with my Mega Disk because I checked it with another working Model 1 Sega Gensis which I use as a tester during my work flow. So that is one issue. The other issue is that the flickering on the screen still didn't tone down. That is when I decided to use my Sega CD power supply to pug it in directly to console, everything worked!! No flicker no nothing!! However I do need a separate ac adapter for the model 1 Sega Genesis. Problem is that getting an original OEM is expensive and I would love to get a replacement that actually works the same way without the screen flicker from the electrical outlet. The other issue is trying to get my Mega Disk to work again and I honestly do not know where to start. Should I replace all capacitor to match the same UF and V on the guide? Or Do I change the voltage regulators?

I apologize for the long post.
