Didier et al, I did not ask for, and did not expect rocket science. Just a simple solution or advice from some of the much more experienced people on this list. I am trying to put my equipment together after having had everything in storage for several years. Being retired and on a limited budget, I am trying to make what I have work, rather than trying to reinvent the wheel.
Given enough time and an unlimited budget, I'm sure that I could come up with a better solution. For the time being, I was hoping that someone on the list could point me to a simple solution that would fit my needs and budget, thinking that lots of other people have had to go through similar steps with the number of Chinese switching power supplies that were sold with the Thunderbolts, both here on the list and on eBay. > just care and good engineering. I totally agree. I did that professionally for many years, but now I'm retired and no longer have access to the resources and test equipment I used to have access to at work. Other people on the list have access to better resources than I do and many people have more experience than I do, especially when it comes to switching power supplies. I appreciate all the advice I was given, although nobody pointed me to a circuit with component values that I could simply duplicate, instead of having to go the whole process of getting my books off the shelf and do what others have already done. No matter now. UPS just brought me a nice linear power supply today. 5 volts @ 28 amps and +/-12 volts @ 3 amps. Although probably many times overkill for the application and as big as breadbox, this should probably work, and without the unnecessary need to add complex (or not) filters.
