A replacment Powersupply for your AMIGA. Update of the old PSU # 391029-03.
Updade: The ripple ist nearly 70 -80 mV p-p! In the video I said 7-8 mV but this is wrong! The damping switch on the probe was set to 10x!
I would like to bring to your attention a problem with the old power supply # 391029-03 for the Amiga 500, Amiga 600 and Amiga 2000. With this particular power supply for the Amiga 1200, I noticed that the output voltages did not work properly. The 5 volt channel had too much ripple. The positive 12 volt output voltage was too high and the negative was not present at all. So I did not connect this to my Amiga 1200, but tried to do a failure analysis. I decided not to repair the board, but to replace it completely, so I thought about what could be a safe replacement for such a power supply. Of course there are the power supplies from Meanwell, they are really cheap. But somehow I didn't feel comfortable with the concept of Meanwell, because I wanted to build an industrial-grade replacement for my power supply, so I looked around for industrial power supplies and came across a very good, but expensive AC-DC converter. It is the AC DC converter from tracopower, more precisely the TMP 30522 C.
